The utility model provides a power electronic transformer relates to electric Railway and pulls power supply technical field. It can be solved developments and administer the negative current and compensate idlely and pull the problem of netting electric phase separating. Adopt a n converter module to cascade input cascade structure double -phase of the formation of meeting single -phase power electronic transformer, use with the cooperation of scott transformer, it is continuous with single -phase power electronic transformerA's positive input terminal A1P that reactance LA is connected to alpha looks output A1P' process, and beta looks output B1P' is continuous with single -phase power electronic transformerB's positive input terminal B1P through connecting reactance LB, and transformerA's negative input end anN and transformer B's negative input end bnN link to each other, when adopting output for parallelly connected structure, transformer A's forward transportation output a1P links to each other with tra
