This report describes the efforts of the Japanese transit industry, which includes manufacturers and transit operators, in the area of advanced propulsion systems for urban rail vehicles. It presents different chopper system designs, new ac drive developments, various commercial frequency and audio frequency signalling systems, investigation of potential electromagnetic interference problems, and possible countermeasures. Six Japanese transit systems using chopper cars are described in some detail in Appendix A and a widely used commutation circuit of these choppers is described in Appendix B. Other related topics, such as equipment reliability and maintenance, are also discussed.
