    Abstract - (Show below) - (Hide below)

    Applicable to all types of semiconducter converters of the self-commutated type, including power converters which contain at least one part of a self-commutated type, for example a.c. converters, direct d.c. converters, indirect d.c. converters. The requirements also apply to self-commutated converters as far as they do not contradict this standard. For some special applications, i.e. uninterruptible power systems, variable speed a.c. and d.c. drives and electric traction equipment, additional standards may apply. Test restrictions may apply to special applications, for example, high-power reactive power converters.
