Standards for Commutating Capacitors

Problems of standardization exist for capacitors used in power semiconductor equipment. Electronic Industries Association (EIA) has taken a step forward in this area by publishing an industry standard for commutating capacitors. Details of definitions, case types, terminals, ratings, measurements, life tests, performance characteristics, and general applications of these capacitors are covered in the proposed standard. This paper describes part of the EIA program and also includes limited information on the design of commutating capacitors and their use in power semiconductor circuits.
