Abstract
A station building power supply device according to the present invention includes: a station building power generation unit including an inverter main circuit and an inverter control circuit to control the inverter main circuit, in which the inverter main circuit converts a voltage supplied from an overhead wire into a voltage required by loads in a station building; a control-circuit power generation unit that converts a voltage supplied to the loads in the station building and generates an input voltage for the inverter control circuit; and a start-up power generation unit that converts a voltage supplied from the overhead wire and generates an input voltage for the inverter control circuit, in a state where the inverter main circuit has stopped the operation and the control-circuit power generation unit has stopped an operation of generating the input voltage for the inverter control circuit.
