Semiconductor convertors. General requirements and line commutated convertors - Self-commutated semiconductor converters including direct d.c. converters Ingestion-build-48183 What is BS EN 50147-11 Scope This part of IEC 60146 applies to all types of semiconductor converters of the selfcommutated type including power converters which contain at least one part of a selfcommutated type, for example a. c. converters, indirect d. c. converters, direct d. c. converters. The requirements of IEC 6014611 apply also to self commutated converters as far as they are not in contradiction with this standard. For some special applications, for example,
