Full title and description

Semiconductor converters - General requirements and line commutated converters - Part 1-2: Application guidelines. This technical report (IEC TR 60146-1-2:2019, edition 5.0) provides guidance on variations to the specifications given in IEC 60146-1-1:2009 and background information to facilitate application of that standard, with particular emphasis on line-commutated converters and certain auxiliary components.

Abstract

IEC TR 60146-1-2:2019 is an application-oriented technical report that complements IEC 60146-1-1:2009 by describing controlled ways to extend specifications for special cases, explaining technical points relevant to users, and giving guidance primarily for line-commutated converters. The 2019 (5th) edition adds annexes and updates calculation methods and references to align with more recent transformer and protective-device guidance.

Scope

This technical report gives guidance on variations to the specifications given in IEC 60146-1-1:2009 so that those specifications can be extended in a controlled way for special cases. It supplies background information on technical points to facilitate the use of IEC 60146-1-1 and addresses primarily line-commutated converters; it is not itself a product-specification standard except insofar as necessary data for certain auxiliary components are provided. The 2019 edition also incorporates annexes and updated calculation and transformer-loss descriptions to align with recent transformer standards.

Key topics and requirements

• Guidance on applying and extending IEC 60146-1-1 requirements for special use-cases involving semiconductor converters.
• Application-focused information for line-commutated converters (design, operation and auxiliary components).
• Addition of annexes addressing use of converter transformers and selection/application of fuses for overcurrent protection.
• Revised calculation methods for inductive voltage regulation and updated descriptions of transformer losses to align with recent transformer standards.
• Updated normative and informative references to reflect developments in related standards and technological practice.

The list above summarizes the principal technical changes and topics emphasized in the 2019 (5th) edition.
