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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
