We built a new electronic frequency converter (EFC) in the Tokaido Shinkansen to replace the rotary frequency changer. The new EFC is individually operated using a basic feeding pattern; these converters require over-current tolerance in the converters. In this paper, we describe the application of EFC to the Shinkansen railyard, showing the development of the control scheme that can control the over-current. The new EFC has a unique feature in connecting pre-existing power supplies apart from the new EFC, for covering various feeding situations. We also describe the interconnection method.
