FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 61800-3 has been prepared by subcommittee 22G: Adjustable speed electric power drive
systems (PDS), of IEC technical committee 22: Power electronic systems and equipment. It is
an International Standard.
It has the status of a product EMC standard in accordance with IEC Guide 107.
This fourth edition cancels and replaces the third edition published in 2017. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) extension of the scope to machine tools with one or more embedded PDS;
b) extension of the frequency range for radiated immunity tests to 6 GHz;
c) general updates in the normative part and the informative annexes.

ADJUSTABLE SPEED ELECTRICAL
POWER DRIVE SYSTEMS –
Part 3: EMC requirements and specific test methods
for PDS and machine tools
1 Scope
This part of IEC 61800 specifies electromagnetic compatibility (EMC) requirements for
adjustable speed power drive systems (PDSs) and machine tools (MTs). A PDS is an AC or DC
motor drive including an electronic converter. Requirements are stated for AC and DC PDSs
and MTs with input and/or output voltages (line-to-line voltage), up to 35 kV AC RMS. This
document applies to equipment of all power ratings.
As a product EMC standard, this document can be used for the assessment of PDS and MT. It
can also be used for the assessment of complete drive modules (CDM) or basic drive modules
(BDM).
NOTE 1 BDMs and CDMs are parts of the PDS which are often marketed separately.
Traction applications and electric vehicles are excluded. Equipment which is defined as group 2
in CISPR 11:2015 is excluded.
NOTE 2 Examples of group 2 equipment are:
– welding equipment (arc welding, resistance welding, etc);
– electro-discharge machining equipment (EDM).
This document does not give requirements for the electrical machine which converts power
between the electrical and mechanical forms within the PDS. Requirements for rotating
electrical machines are covered by the IEC 60034 series. In this document, the term "motor" is
used to describe the electrical machine, whether rotary or linear, and regardless of the direction
of power flow.
This document is applicable to BDMs, CDMs, PDSs and MTs with or without radio function.
However, this document does not specify any radio transmission and reception requirements.
NOTE 3 It is planned that the future edition 7 of CISPR 11 will contain a procedure how to address radio
transmission and reception requirements, which is also applicable to products in the scope of this document.
This document defines the minimum requirements for emission and immunity in the frequency
range from 0 Hz to 400 GHz. Tests are not required in frequency ranges where no requirements
are specified.
BDMs, CDMs, PDSs and MTs covered by this document are those installed in residential,
commercial and industrial locations. Requirements are given according to the environment
classification.
BDMs, CDMs and PDSs are often included in a larger system. The system aspects are not
covered by this document, but guidance is provided in the informative annexes.
___________
Under preparation. Stage at the time of publication: CISPR/NFDIS 11:2022.

– 10 – IEC 61800-3:2022 © IEC 2022
This document is intended as a complete product EMC standard for the EMC conformity
assessment of products. As a product EMC standard for BDMs, CDMs, PDSs and MTs,
according to IEC Guide 107, this document takes precedence over all aspects of the generic
standards.
NOTE 4 If a PDS or MT is included as part of equipment covered by a separate product EMC standard, the separate
EMC standard applies to the complete equipment.
NOTE 5 The requirements have been selected to ensure EMC for PDSs and MTs at residential, commercial and
industrial locations. Changes in the EMC behaviour of a PDS or an MT as a result of fault conditions are not
considered.
NOTE 6 This document does not specify any safety requirements for the equipment such as protection against
electric shocks, insulation co-ordination and related dielectric tests, unsafe operation, or unsafe consequences of a
failure. It also does not cover safety and functional safety implications of electromagnetic phenomena.
