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 61800-3 has been prepared by sub-committee 22G: Adjustable
speed electric drive systems incorporating semiconductor power converters, of IEC technical
committee 22: Power electronic systems and equipment.
This second edition cancels and replaces the first edition issued in 1996 and constitutes a
technical revision.
This second edition introduces three main changes:
a) the classes of distribution (unrestricted and restricted) of the PDS have been replaced by
categories of PDS (C1 to C4) with definitions related to the product itself and its intended
use;
b) better coverage of emission limits;
c) an EMC plan is generalized for category C4.

ADJUSTABLE SPEED ELECTRICAL POWER
DRIVE SYSTEMS –
Part 3: EMC requirements and specific test methods
1 Scope and object
This part of IEC 61800 specifies electromagnetic compatibility (EMC) requirements for power
drive systems (PDSs). A PDS is defined in 3.1. These are adjustable speed a.c. or d.c. motor
drives. Requirements are stated for PDSs with converter input and/or output voltages (line-to-
line voltage), up to 35 kV a.c. r.m.s.
PDSs covered by this standard are those installed in residential, commercial and industrial
locations with the exception of traction applications, and electric vehicles. PDSs may be
connected to either industrial or public power distribution networks. Industrial networks are
supplied by a dedicated distribution transformer, which is usually adjacent to or inside the
industrial location, and supplies only industrial customers. Industrial networks can also be
supplied by their own electric generating equipment. On the other hand, PDSs can be directly
connected to low-voltage public mains networks which also supply domestic premises, and in
which the neutral is generally earthed (grounded).
The scope of this part of IEC 61800, related to EMC, includes a broad range of PDSs from a
few hundred watts to hundreds of megawatts. PDSs are often included in a larger system. The
system aspect is not covered by this standard but guidance is provided in the informative
annexes.
The requirements have been selected so as to ensure EMC for PDSs at residential,
commercial and industrial locations. The requirements cannot, however, cover extreme cases
which may occur with an extremely low probability. Changes in the EMC behaviour of a PDS,
as a result of fault conditions, are not taken into account.
The object of this standard is to define the limits and test methods for a PDS according to its
intended use. This standard includes immunity requirements and requirements for electro-
magnetic emissions.
NOTE 1 Emission can cause interference in other electronic equipment (for example radio receivers, measuring
and computing devices). Immunity is required to protect the equipment from continuous and transient conducted
and radiated disturbances including electrostatic discharges. The emission and immunity requirements are
balanced against each other and against the actual environment of the PDS.
This standard defines the minimum EMC requirements for a PDS.
Immunity requirements are given according to the environment classification. Low-frequency
emission requirements are given according to the nature of the supply network. High-
frequency emission requirements are given according to four categories of intended use,
which cover both environment and bringing into operation.
As a product standard, this standard may be used for the assessment of PDS. It may also be
used for the assessment of CDM or BDM (see 3.1), which can be marketed separately.

61800-3 ” IEC:2004 – 17 –
This standard contains:
– conformity assessment requirements for products to be placed on the market;
– recommended engineering practice (see 6.5) for cases where high frequency emissions
cannot be measured before the equipment is placed on the market (such PDSs are
defined in 3.2.6 as category C4).
NOTE 2 The first edition of IEC 61800-3 identified that the intended use could require engineering for putting into
service. This was done by the “restricted distribution mode”. Equipment that used to be covered by the “restricted
distribution mode” is covered in the second edition by categories C2 and C4 (see 3.2).
This standard is intended as a complete EMC product standard for the EMC conformity
assessment of products of categories C1, C2 and C3, when placing them on the market (see
definitions 3.2.3 to 3.2.5).
Radio frequency emission of equipment of category C4 is only assessed when it is installed in
its intended location. It is therefore treated as a fixed installation, for which this standard
gives rules of engineering practice in 6.5 and annex E, although it gives no defined emission
limits (except in case of complaint).
This standard 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.
In special cases, when highly susceptible apparatus is being used in proximity, additional
mitigation measures may have to be employed to reduce the electromagnetic emission further
below the specified levels or additional countermeasures may have to be employed to
increase the immunity of the highly susceptible apparatus.
As an EMC product standard for PDSs, this standard takes precedence over all aspects of the
generic standards and no additional EMC tests are required or necessary. If a PDS is
included as part of equipment covered by a separate EMC product standard, the EMC
standard of the complete equipment applies.

3 Terms and definitions
3.1 Overview
For the purposes of this document, definitions related to EMC and to relevant phenomena to
be found in IEC 60050(161), in CISPR, and also, the following additional definitions apply.
A power drive system (PDS) consists of a motor and a complete drive module (CDM). It does
not include the equipment driven by the motor. The CDM consists of a basic drive module
(BDM) and its possible extensions such as the feeding section or some auxiliaries (e.g.
ventilation). The BDM contains converter, control and self-protection functions. Figure 1
shows the boundary between the PDS and the rest of the installation and/or manufacturing
process. IEC 61800-1, IEC 61800-2 and IEC 61800-4 give details for these definitions.
