Introduction
This Technical Specification defines characteristics and interfaces for electric onboard auxiliary power
converter systems. This includes auxiliary power converters and battery chargers. The following
European Standards and Technical Specifications refer to the defined target energy supply system in
this present Technical Specification:
CLC/TS 50534 Railway applications – Generic system architectures for onboard electric
auxiliary power systems
(Characteristics and interface of generic system architectures for onboard
electric auxiliary power systems)
1)
EN 50533 Railway applications – Three-phase train line voltage characteristics
(Characteristics of the voltage system used for auxiliary power supply)
2)
EN 50546 Railway applications – Shore (external) supply system for rail vehicles
(Interface description of the shore supply including protection functions)
2)

(Standardized batteries for rail vehicles and charging characteristics)
CLC/TS 50537 (series) Railway applications – Mounted parts of the traction transformer and
cooling system
(Standardized products used in conjunction with traction transformers and
traction cooling systems)
CLC/TS 50535 has to be understood as a basic document of a set of hierarchically structured
specifications as illustrated in the foreword. This set of European Standards and Technical
Specifications defines a consistent technical framework beginning on an architectural level, followed
by standards belonging to important system interfaces and concluding this hierarchy with Technical
Specifications on component level. The diagram in the foreword points up these different system
integration levels and shows the dependencies between the documents.
One main objective of this standardisation initiative is to simplify the cooperation between concerned
railway stakeholders in charge of operating onboard auxiliary power systems, designing systems able
to cope with the operational requirements and stakeholders manufacturing auxiliary power system
components, which provide the requested services.

1 Scope
This Technical Specification defines the classification of the electric onboard auxiliary power converter
system and defines its basic characteristics and interfaces. The onboard auxiliary power converter
system consists of the auxiliary converter and the battery charger function.
This Technical Specification applies to locomotive hauled passenger trains and electric multiple units
with distributed power as well as trains with concentrated power heads. Relevant train configuration
and concerned energy supply subsystems are defined in CLC/TS 50534. This Technical Specification
provides a technical base for implementation of onboard auxiliary power systems on different trains.
The objective of this specification is to define the required interfaces and characteristics of the
onboard auxiliary power converter system in order to enable further standardisation:
• interface between onboard auxiliary power converter system and onboard traction power system;
• interface of the onboard auxiliary power supply system to the low voltage grid and to a shore
supply (stationary workshop supply or external supply);
• interfaces of the auxiliary converter and the battery charger;
• characteristics of the onboard auxiliary power converter system.
The electrical operational behaviour is defined by requirements. Requirements for the type tests as
well as the routine test are referred.

4.1 Definitions for onboard auxiliary power converter systems
General requirements of the electronics systems installed in the rail vehicles are defined in
EN 61287-1. Onboard auxiliary power converter systems are an integral part of the electrical system in
trains. They are a collection of power components that convert, manage and distribute electrical power
from the input source(s) to the auxiliary loads.
