IEC 60146:1973

Specifies the requirements for the performance of all electronic power convertors and electronic power switches using controllable and/or non-controllable electronic valves. Specifies the requirements applicable to line commutated convertors for conversion of a.c. power to d.c. power or vice versa including tests and service conditions which influence the basis of rating. The contents of the corrigendum of August 1993 have been included in this copy.

Applies to all types of semiconductor convertors, i.e. d.c. to d.c. convertors without an a.c. link. If applicable, it may also be used for certain d.c. switches in control applications. Gives terminology and specifies service conditions, rated values, test programme and test methods.

Applies to all types of semiconductor inverters of the self-commutated type and semiconductor convertors which contain at least one part of a self-commutated type, including direct a.c. convertors and d.c. convertors for all applications.
