General Information
Frequently Asked Questions
MT 20 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 22/SC 22G/MT 20". This committee has published 25 standards.
MT 20 develops IEC standards in the area of Information technology. Currently, there are 25 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC 61800-1:2021 applies to adjustable speed electric DC power drive systems, which include semiconductor power conversion and the means for their control, protection, monitoring, measurement and the DC motors.
It applies to adjustable speed electric power drive systems intended to feed DC motors from a BDM/CDM connected to line-to-line voltages up to and including 1 kV AC 50 Hz or 60 Hz and/or voltages up to and including 1,5 kV DC input side.
NOTE 1 Adjustable speed electric AC power drive systems intended to feed AC motors are covered by
IEC 61800-2.
NOTE 2 This document can be used as a reference for adjustable speed electric power drive systems, intended to feed DC motors from a BDM/CDM connected to line-to-line voltages up to and including 1,5 kV AC, 50 Hz or 60 Hz and/or voltages up to and including 2,25 kV DC input side.
This edition includes the following significant technical changes with respect to the previous edition:
a) the clause structure has been harmonized with IEC 61800-2;
b) Clause 2 has been updated;
c) Clause 3 has been updated including fundamental definitions to be used across IEC 61800 (all parts);
d) Clause 4 has been updated with respect to:
1) description of the basic topology for BDM/CDM/PDS (4.2);
2) ratings and performance (4.3 and 4.4);
3) reference to applicable standards within the IEC 61800 series with respect to EMC (IEC 61800-3), general safety (IEC 61800-5-1), functional safety (IEC 61800-5-2), load duty aspects (IEC TR 61800-6), communication profiles (IEC 61800-7 series),power interface voltage (IEC TS 61800-8), and ecodesign energy efficiency standards (IEC 61800-9) to avoid conflicting requirements (4.5, 4.6, 4.7, 4.10, 4.11, 4.12);
4) update of requirement for ecodesign (4.8);
5) update of requirement for environmental evaluation (4.9);
6) implementation of requirement for explosive atmosphere (4.13);
e) Clause 5 has been updated with test requirement in order to provide a clear link between design requirement and test requirement;
f) Clause 6 has been updated to harmonize the marking and documentation requirement within IEC 61800 (all parts);
g) the Annexes have been updated.
