ADJUSTABLE SPEED ELECTRICAL POWER DRIVE SYSTEMS –
Part 6: Guide for determination of types of load duty
and corresponding current ratings
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 technical report may be the subject of
patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example “state of the art”.
IEC 61800-6, which is a technical report, has been prepared by subcommittee 22G: Semi-
conductor power converters for adjustable speed electric drive systems, of IEC technical
committee 22: Power electronics systems and equipment.
This first edition cancels and replaces IEC 61136-1, issued in 1992, and constitutes a
technical revision.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
22G/85/DTR 22G/100/RVC
Full information on the voting for the approval of this technical report can be found in the report
on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

TR 61800-6 © IEC:2003 – 7 –
The committee has decided that the contents of this publication will remain unchanged until
2008. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

Part 6: Guide for determination of types of load duty
and corresponding current ratings
1 General
1.1 Scope and object
This technical report provides alternative methods for specifying ratings for adjustable speed
electrical power drive systems (PDS) and in particular their basic drive modules (BDM).
It is not intended to cover adjustable speed drives for traction purposes.
General rules for rating specification for low voltage adjustable speed d.c. power drive systems
are contained in IEC 61800-1, and for low voltage adjustable frequency a.c. power drive
systems in IEC 61800-2.
1.2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of
the referenced document (including any amendments) applies.
