Title: AUXILIARY POWER SUPPLY DEVICE FOR STATION BUILDINGS
Abstract:
This auxiliary power supply device for station buildings is equipped with: an operation start determination unit 21 that determines whether to convert a first AC power on the AC overhead line side into a second AC power available for loads, on the basis of a first signal, which is flow direction information showing the flow direction of power between an AC overhead line connected to electric vehicles and a substation supplying AC power to the AC overhead line, and, upon determining to perform the conversion, generates and outputs a second signal; a voltage instruction value calculation unit 22 that calculates and outputs a voltage instruction value corresponding to the second signal; and a PWM signal generation unit 23 that generates and outputs a control signal to a power converter circuit driven when converting the first AC power into the second AC power on the basis of the voltage instruction value.
