Ripple on d.c. input power port immunity test

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61000-4-17 has been prepared by subcommittee 77A: Low-
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
It forms part 4-17 of IEC 61000. It has the status of a basic EMC publication in accordance with
IEC Guide 107.
This consolidated version of IEC 61000-4-17 consists of the first edition (1999) 77A/271/FDIS
and 77A/280/RVD] and its amendment 1 (2001) 77B/291+293/FDIS and 77B/298+300/RVD].

The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 1.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
Annex A is for information only.
The committee has decided that the contents of the base publication and its amendment will

Essai d’immunité à l’ondulation résiduelle sur entrée de puissance

à courant continu
1 Domaine d’application
La présente partie de la CEI 61000 définit les méthodes d'essai d'immunité aux ondulations
résiduelles appliquées à l'entrée de l'alimentation à courant continu des matériels électriques
ou électroniques.
La présente norme s’applique aux entrées de puissance à courant continu basse tension des
matériels alimentés par des systèmes redresseurs externes ou par des batteries qui sont en
charge.
L’objet de la présente norme est d’établir une base commune et reproductible pour les essais
afin d’évaluer en laboratoire la performance des matériels électriques et électroniques
lorsqu’ils sont soumis à des tensions d’ondulation résiduelle, comme par exemple celles qui
sont produites par les systèmes redresseurs et/ou les chargeurs de batteries auxiliaires
superposés à des sources d’alimentation à courant continu.
La présente norme définit
– la forme d’onde de la tension d’essai;
– une gamme de niveaux d’essai;
– le générateur d’essai;
– l'installation d’essai;
– la procédure d’essai.
L'essai décrit ci-après s'applique aux matériels et systèmes électriques ou électroniques.
Il s'applique également aux modules ou aux sous-systèmes lorsque la puissance assignée de
l'équipement sous test (EST) est supérieure à la capacité du générateur d'essai spécifiée à
l'article 6.
Le présent essai ne s’applique pas aux matériels reliés aux systèmes de chargeurs de batterie
comprenant des convertisseurs à découpage.

La présente norme ne précise pas les essais à effectuer sur des appareils ou systèmes
particuliers. Son objectif principal est de fournir une référence générale de base à tous les
comités de produits concernés au sein de la CEI. Ces comités de produits (ou les utilisateurs
ou les fabricants de matériels) restent responsables du choix approprié de l’essai et du niveau
de sévérité à appliquer à leurs matériels.
Des procédures d'essai dédiées sont utilisées pour soumettre à essai des catégories
spécifiques de matériels électriques ou électroniques, par exemple le matériel connecté au
réseau d'alimentation en courant continu de centres de commutation téléphoniques; il convient
que les comités de produits correspondants évaluent la pertinence et l'applicabilité de la
procédure d'essai spécifiée dans la présente norme fondamentale.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 4-17: Testing and measurement techniques –

Ripple on d.c. input power port immunity test

1 Scope
This part of IEC 61000 defines test methods for immunity to ripple at the d.c. input power port
of electrical or electronic equipment.
This standard is applicable to low-voltage d.c. power ports of equipment supplied by external
rectifier systems, or batteries which are being charged.
The object of this standard is to establish a common and reproducible basis for testing, in a
laboratory, electrical and electronic equipment when subjected to ripple voltages such as those
generated by rectifier systems and/or auxiliary service battery chargers overlaying on d.c.
power supply sources.
This standard defines
– test voltage waveform;
– range of test levels;
– test generator;
– test set-up;
– test procedure.
The test described hereafter applies to electrical or electronic equipment and systems. It also
applies to modules or subsystems whenever the equipment under test (EUT) rated power is
greater than the test generator capacity specified in clause 6.
This test does not apply to equipment connected to battery charger systems incorporating
switch mode converters.
This standard does not specify the tests to be applied to particular apparatus or systems. Its
main aim is to give a general basic reference to IEC product committees. These product
committees (or users or manufacturers of equipment) remain responsible for the appropriate

choice of the test and the severity level to be applied to their equipment.
Dedicated test procedures are in use for testing specific categories of electrical or electronic
equipment, e.g. equipment connected to d.c. supply network of telephone switching centres;
the related product committees should evaluate the relevance and applicability of the test
procedure specified in this basic standard.

3 Généralités
L’ondulation résiduelle peut influer sur la fiabilité du fonctionnement des matériels et des
systèmes, alimentés en courant continu, et installés dans des installations industrielles, rési-
dentielles ou commerciales.
La perturbation par ondulation résiduelle est représentée par la tension dérivée d’une grandeur
impulsionnelle de laquelle la composante directe a été retirée.
Les principales sources de perturbation par ondulation résiduelle sont les systèmes
redresseurs utilisés dans les réseaux de puissance externes à courant continu et les chargeurs
de batteries.
L’ondulation résiduelle est par conséquent un phénomène présent en permanence dans ce
type de source de puissance à courant continu, et elle peut s’accentuer lors du rechargement
de la batterie pendant le rétablissement du service de la ligne de courant alternatif.
Les composantes de l’ondulation résiduelle peuvent aussi être produites par des matériels
absorbant un courant impulsionnel, mais ces composantes ne sont pas du domaine de la
présente norme.

3 General
Ripple may influence the reliable operation of equipment and systems, powered by d.c.
supplies, installed in industrial plants as well in residential and commercial installations.
The ripple disturbance is represented by the voltage derived from a pulsating quantity from
which the direct component has been removed.
The main sources of ripple disturbance are rectifier systems used in the external d.c. power
networks and battery chargers.
Ripple is therefore a phenomenon continuously present in this type of d.c. power source, and
may be accentuated when the battery is recharging after a recovery of the a.c. power line
service.
Ripple components may also be produced by equipment absorbing a pulsating current; this is
not covered in this standard.

For the purpose of this part of IEC 61000 the following definitions apply, together with the
definitions of IEC 60050(161) [IEV].

Ripple on d.c. input power port immunity test

1 Scope
This part of IEC 61000 defines test methods for immunity to ripple at the d.c. input power port
of electrical or electronic equipment.
This standard is applicable to low-voltage d.c. power ports of equipment supplied by external
rectifier systems, or batteries which are being charged.
The object of this standard is to establish a common and reproducible basis for testing, in a
laboratory, electrical and electronic equipment when subjected to ripple voltages such as those
generated by rectifier systems and/or auxiliary service battery chargers overlaying on d.c.
power supply sources.
This standard defines
– test voltage waveform;
– range of test levels;
– test generator;
– test set-up;
– test procedure.
The test described hereafter applies to electrical or electronic equipment and systems. It also
applies to modules or subsystems whenever the equipment under test (EUT) rated power is
greater than the test generator capacity specified in clause 6.
This test does not apply to equipment connected to battery charger systems incorporating
switch mode converters.
This standard does not specify the tests to be applied to particular apparatus or systems. Its
main aim is to give a general basic reference to IEC product committees. These product
committees (or users or manufacturers of equipment) remain responsible for the appropriate
choice of the test and the severity level to be applied to their equipment.
Dedicated test procedures are in use for testing specific categories of electrical or electronic
equipment, e.g. equipment connected to d.c. supply network of telephone switching centres;
the related product committees should evaluate the relevance and applicability of the test
procedure specified in this basic standard.

3 General
Ripple may influence the reliable operation of equipment and systems, powered by d.c.
supplies, installed in industrial plants as well in residential and commercial installations.
The ripple disturbance is represented by the voltage derived from a pulsating quantity from
which the direct component has been removed.
The main sources of ripple disturbance are rectifier systems used in the external d.c. power
networks and battery chargers.
Ripple is therefore a phenomenon continuously present in this type of d.c. power source, and
may be accentuated when the battery is recharging after a recovery of the a.c. power line
service.
Ripple components may also be produced by equipment absorbing a pulsating current; this is
not covered in this standard.
4 Definitions
For the purpose of this part of IEC 61000 the following definitions apply, together with the
definitions of IEC 60050(161) [IEV].

The preferred range of test levels, applicable to the d.c. power supply port of the equipment,
are given in table 1.

max min
The frequency of the ripple is the power frequency or its multiple 2, 3 or 6, as specified by a
product committee or according to the EUT manufacturer’s specifications or according to the
characteristics of the rectifier system (see also clause A.2).
The waveform of the ripple voltage, at the output of the test generator, has a sinusoid-linear
character.
A sinusoidal-linear characteristic can be described as a part of a sine wave and a line, tangent
to the decreasing side of the rectified wave, that intersects the rising edge of the following half-
wave; the voltage difference between the peak value of the sine wave and the point of
intersection to the following half-wave is the ripple voltage (see figure 1). The decreasing
voltage can be assumed as a linear function in the presence of constant current loads. The
voltage deviation, in the case of a constant resistor or constant power load, is very small and
can be considered acceptable for the purpose of the test.
Deviations from the defined waveform, due to the impedance of the EUT, are allowed during
the test. However, care should be taken in order to assess that the deviation from the original
waveform is not caused by limitation of the generator. Furthermore, the peak-to-peak value and
the frequency of ripple shall be maintained by adjustment in order to maintain the severity of
the test.
The graphical representation of the waveform obtained from a single-phase bridge and a three-
phase bridge rectifier is shown in figure 1; the difference U – U is the percentage of the
max min
nominal d.c. voltage and corresponds to the selected test level.
NOTE  Information on the phenomenon and on the selection of the test level is given in annex A, clauses A.1
and A.2.

6 Test generator
6.1 Characteristics and performance of the generator
The test generator shall be able to operate in continuous mode with the following main
specifications:
– output voltage range: up to 360 V;
– output voltage change with load: less than 5 %;
(0 to rated current)
– output voltage waveform: alternating component at power frequency or its
multiple, with a sinusoid-linear character,
superimposed on the d.c. voltage
– output voltage tolerance: ±10 %
– output current (steady state): up to 25 A;
– peak output current capability: +2,5/–0,5 times the steady-state current;
(maximum allowable duration 5 ms)
– ripple frequency tolerance: ±1 %.
NOTE  The 360 V output voltage value covers the test condition of a 300 V d.c. supply voltage plus a 15 % ripple
corresponding to test level 4.
The use of a generator with higher or lower voltage/current capability is allowed provided that
the other specifications (waveform, change with load, peak output current/steady-state current
ratio, etc.) are preserved. The test generator output power/current capability shall be at least
20 % greater than the EUT power/current ratings.
The generator must be able to produce positive and negative peak current with positive voltage
output.
Examples of generators can be found in clause A.3.
Figure A.1 shows a schematic diagram of a generator based on a rectifier system; figure A.2
shows a schematic diagram of a generator based on a programmable power supply with
controller.
6.2 Verification of the characteristics of the generator
In order to compare the test results the following characteristics of the generator shall be
verified:
– the sinusoid-linear character of the ripple signal shall be maintained at maximum output
voltage, with the output connected to a resistive load of 60 Ω;
– the sinusoid-linear character of the ripple signal shall be maintained at maximum current
(25 A), with the output connected to a resistive load (e.g. 2,4 Ω at output voltage of 60 V);
– the ripple frequency;
– the peak output current shall meet the requirements of 6.1, when switching the generator
output from 0 V to 60 V and driving an uncharged capacitor whose value is at least
1 700 μF.
The verification of a generator with voltage/current capability less than specified in 6.1 shall be
made with load conditions reflecting the rated voltage and current.
The measurement uncertainty of the instrumentation (e.g. low-frequency oscilloscope, d.c.
voltmeter and a.c. peak-to-peak voltmeter) shall be less than or equal to 2 %.

7 Test set-up
The test shall be performed with the EUT connected to the test generator with the shortest
power supply cable as specified by the manufacturer. If no cable length is specified, it shall be
the shortest practical length suitable for the connection of the EUT.
8 Test procedure
The test procedure shall include the following:
– verification of the laboratory reference conditions;
– preliminary verification of the correct operation of the equipment;
– execution of the test;
– evaluation of the test results.
8.1 Laboratory reference conditions
In order to minimize the impact of environmental parameters on test results, the tests shall be
performed in climatic and electromagnetic reference conditions as specified in 8.1.1 and 8.1.2.
8.1.1 Climatic conditions
Unless otherwise specified by the committee responsible for the generic or product standard,
the climatic conditions in the laboratory shall be within any limits specified for the operation of
the EUT and the test equipment by their respective manufacturers.
Tests shall not be performed if the relative humidity is so high as to cause condensation on the
EUT or the test equipment.
NOTE Where it is considered that there is sufficient evidence to demonstrate that the effects of the phenomenon
covered by this standard are influenced by climatic conditions, this should be brought to the attention of the
committee responsible for this standard.
8.1.2 Electromagnetic conditions
The electromagnetic conditions of the laboratory shall be such as to guarantee the correct
operation of the EUT in order not to influence the test results.
8.2 Execution of the test
The EUT shall be configured for its normal operating conditions. The test shall be performed
according to a test plan that shall specify:
– test level;
– duration of the test;
– representative operating conditions of the EUT;
– auxiliary equipment.
The power supply, signal and other functional electrical quantities shall be applied within their
rated range. Signal and other functional electrical quantities may be simulated.

61000-4-17 © IEC:1999+A1:2001 – 11 –
+A2:2008
It is recommended that a preliminary verification of the EUT's performance be made on the
complete test set-up before applying the test voltage.
The test voltage, corresponding to the selected level, shall be applied to the d.c. port of the
EUT; the values of the d.c. voltage and the ripple content (peak to peak) shall be measured at
the terminals of the EUT and adjusted in order to maintain the selected test level. The
measurement uncertainty of the instrumentation shall be better than 2 %.
The average value U of the waveform resulting from the d.c. voltage with the superimposed
d.c. ,
ripple content, shall numerically be equal to the rated voltage of the EUT (see figure 1).
The test shall then be repeated with U at the lower value of the voltage range.
d.c.
Additional test voltages (e.g. the higher value of the voltage range) may be defined by product
committees.
NOTE  The test at the lower value of the voltage range generally covers the most severe conditions.
The test voltage shall be applied for at least 10 min or for the period of time necessary to allow
a complete verification of the EUT's operating performance.
The waveform of the ripple voltage shall be recorded and included in the test report.
9 Evaluation of test results
The test results shall be classified in terms of the loss of function or degradation of
performance of the equipment under test, relative to a performance level defined by its
manufacturer or the requestor of the test, or agreed between the manufacturer and the
purchaser of the product. The recommended classification is as follows:
a) normal performance within limits specified by the manufacturer, requestor or purchaser;
b) temporary loss of function or degradation of performance which ceases after the
disturbance ceases, and from which the equipment under test recovers its normal
performance, without operator intervention;
c) temporary loss of function or degradation of performance, the correction of which requires
operator intervention;
d) loss of function or degradation of performance which is not recoverable, owing to damage
to hardware or software, or loss of data.
The manufacturer’s specification may define effects on the EUT which may be considered
insignificant, and therefore acceptable.
This classification may be used as a guide in formulating performance criteria, by committees
responsible for generic, product and product-family standards, or as a framework for the
agreement on performance criteria between the manufacturer and the purchaser, for example
where no suitable generic, product or product-family standard exists.

10 Test report
The test report shall contain all the information necessary to reproduce the test. In particular,
the following shall be recorded:
– the items specified in the test plan required by clause 8 of this standard;
– identification of the EUT and any associated equipment, for example, brand name, product
type, serial number;
– identification of the test equipment, for example, brand name, product type, serial number;

generic, product or product-family standard, or agreed between the manufacturer and the
purchaser);
– any specific conditions of use, for example cable length or type, shielding or grounding, or
EUT operating conditions, which are required to achieve compliance.

Annex A
(informative)
Information on the phenomenon
A.1 Description of the phenomenon
The main source of this disturbance is alternating voltage components generated by battery
chargers during their operation, superimposed on the d.c. voltage of distribution systems.
Battery chargers can use different methods of rectification; the most common solutions are
based on a single-phase bridge, three-phase half-wave, a three-phase bridge and six-phase
star.
The particular characteristics of the rectifier circuit considered, at the design level, are
– the ratio between the r.m.s. input voltage and d.c. output voltage;
– the d.c. current for the rectifier unit;
– the amplitude and the frequency of the alternative component superimposed on the d.c.
voltage (ripple).
The amplitude of the ripple is related to the number of the rectifier units. An increase in the
number of units produces a decrease of the ripple voltage and an increase in the ripple
frequency.
The typical waveform of the ripple voltage, in case of linear loads and capacitive filters, is
shown in figure 1. Non-linear loads (e.g. a d.c./d.c. converter unit) may exhibit different
behaviour.
In this latter condition, if the converter is powered with a source affected by high ripple
voltages, a negative current, flowing from the load to the source, can be expected.
A.2 Selection of the test level
The selection of the test level should take into account the characteristics of the rectifier
system and/or the possible operating conditions during the life cycle of the battery (normal life,
wear-out period).
The test levels listed in table 1 are not frequency dependent; however, the lower levels are
generally representative of rectifier systems with a high number of rectifier units and
consequently high-frequency ripples.
As an example, six-star rectifier systems can produce 14 % ripple on a purely resistive load;
when connected to battery systems, the ripple will be substantially lower.
If the type of rectifier and the related operating conditions are not known, the test level selected
should include an appropriate margin for error.
