摘要

PURPOSE: An auxiliary power driving device of a railway vehicle is provided to increase the operation efficiency of a railway vehicle by recharging a battery by using a wiring voltage. CONSTITUTION: A converter(10) outputs driving voltage for changing wiring voltage and driving load. A converter controller(20) outputs a converter control signal by controlling on/off of a switching element that is equipped with a converter. A storage battery(30) supplies first operating voltage. A second working voltage supply unit(40) successively changes outside receiving voltage and wiring voltage that is provided from the outside power receiving apparatus.
