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.

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.

ADJUSTABLE SPEED ELECTRICAL POWER DRIVE SYSTEMS –
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.

IEC 60146-1-1, Semiconductor convertors – General requirements and line commutated

convertors – Part 1-1: Specifications of basic requirements

IEC 61800-1, Adjustable speed electrical power drive systems – Part 1: General requirments –

Rating specifications for low voltage adjustables speed d.c. power drive systems

Rating specifications for low voltage adjustable frequency a.c. power drive systems

2 Terms, definitions and symbols
2.1 Terms and definitions

For the purpose of this technical report the definitions given in IEC 61800-1, IEC 61800-2 and

IEC 60146-1-1 as well as the following, apply.
2.1.1
equilibrium temperature

steady-state temperature reached by a component of a converter under specified conditions of

load and cooling

NOTE Steady-state temperatures are in general different for different components. The times necessary to

establish the steady state are also different and proportional to thermal time constants.

---------------------- Page: 9 ----------------------
TR 61800-6 © IEC:2003 – 11 –
2.1.2
current-time load chart
record of load current with respect to time
2.1.3
uniform load duty

duty for which a converter equipment carries a current of fixed value for an interval sufficiently

long for the components of the converter to reach equilibrium temperatures corresponding to

the said value of current. Figure 1 illustrates this type of load duty (see Table 1 for symbols).

Figure 1 – Typical current-time chart for uniform load duty
2.1.4
intermittent peak load duty

type of duty for which loads of high magnitude and short duration are applied following no-load

periods such that thermal equilibrium is reached between successive applications of the load.

Figure 2 illustrates this type of load duty. The intermittent loads need not be equidistant, but

the minimum value of t to achieve no-load semiconductor temperature before the next

intermittent load should be specified by the manufacturer.

2.1.5
intermittent load duty

type of duty for which intermittent loads are superimposed onto a constant base load such that

thermal equilibrium is reached between successive applications of the intermittent load.

Figure 3 illustrates this type of load duty. The intermittent loads need not be equidistant, but

the minimum value of t to achieve steady state semiconductor temperature before the next

intermittent load is applied should be specified by the manufacturer.

2.1.6
intermittent load duty with no-load intervals

type of duty for which intermittent no-load intervals followed by high load intervals are

superimposed onto a constant base load, such that thermal equilibrium is reached between

successive applications of the intermittent load. Figure 4 illustrates this type of load duty. The

intermittent loads need not be equidistant, but the minimum value of t to achieve steady state

semiconductor temperature before the next intermittent load is applied should be specified by

the ma
