IEC 60146-1-1:2009 specifies the requirements for the performance of all semiconductor power converters and semiconductor power switches using controllable and/or non-controllable electronic valve devices. It is primarily intended to specify the basic requirements for converters in general and the requirements applicable to line commutated converters for conversion of a.c. power to d.c. power or vice versa. Parts of this standard are also applicable to other types of electronic power converter provided that they do not have their own product standards. This fourth edition constitutes a technical revision and introduces five main changes:
- re-edition of the whole standard according to the current directives;
- correction of definitions and addition of new terms, especially terms concerning EMC, harmonic distortion and insulation co-ordination;
- the service condition tolerances have been revised according to the IEC 61000 series;
- the insulation tests have been revised considering the insulation co-ordination;
- addition of three annexes.

GENERAL REQUIREMENTS AND LINE COMMUTATED CONVERTERS –
Part 1-1: Specification of basic requirements
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.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.
International Standard IEC 60146-1-1 has been prepared by IEC technical committee 22:
Power electronic systems and equipment.This fourth edition cancels and replaces the third edition published in 1991, Corrigendum 1
(1993) and Amendment 1 (1996). This fourth edition constitutes a technical revision.
This fourth edition introduces five main changes:a) re-edition of the whole standard according to the current directives;
b) correction of definitions and addition of new terms, especially terms concerning EMC,
harmonic distortion and insulation co-ordination;c) the service condition tolerances have been revised according to the IEC 61000 series;
d) the insulation tests have been revised considering the insulation co-ordination;
e) addition of three annexes.---------------------- Page: 7 ----------------------

SEMICONDUCTOR CONVERTERS –
GENERAL REQUIREMENTS AND LINE COMMUTATED CONVERTERS –
Part 1-1: Specification of basic requirements
1 Scope and object
This International Standard specifies the requirements for the performance of all
semiconductor power converters and semiconductor power switches using controllable and/or
non-controllable electronic valve devices.The electronic valve devices mainly comprise semiconductor devices, either not controllable
(i.e. rectifier diodes) or controllable (i.e. thyristors, triacs, turn-off thyristors and power
transistors). The controllable devices may be reverse blocking or reverse conducting and
controlled by means of current, voltage or light. Non-bistable devices are assumed to be
operated in the switched mode.This standard is primarily intended to specify the basic requirements for converters in general
and the requirements applicable to line commutated converters for conversion of a.c. power to
d.c. power or vice versa. Parts of this standard are also applicable to other types of electronic
power converter provided that they do not have their own product standards.These specific equipment requirements are applicable to semiconductor power converters
that either implement power conversion or use commutation (for example semiconductor self-
commutated converters) or involve particular applications (for example semiconductor
converters for d.c. motor drives) or include a combination of said characteristics (for example
direct d.c. converters for electric rolling stock).This standard is applicable to all power converters not covered by a dedicated product
standard, or if special features are not covered by the dedicated product standard. Dedicated
product standards for power converters should refer to this International Standard.
NOTE 1 This standard is not intended to define EMC requirements. It covers all phenomena and therefore
introduces references to dedicated standards which are applicable according to their scope.
NOTE 2 A large part of this standard, particularly for power transformers, is covered in IEC 61378-1.
