To obtain a drive power supply apparatus for vehicles whose operation can be continued without influence on a drive system or an electrical load when a failure occurs in a power supply system.
The drive power supply apparatus includes a first power supply device 3 that supplies power to a rotary electric machine through an inverter 2 between the power supply device and the rotary electric machine 1 and receives regenerative power from the rotary electric machine, a second power supply device 4 that can be charged and discharged faster than the first power supply device is, a voltage conversion device 5 that is connected between a power supply line SL connecting together the first power supply device 3 and the inverter 2 and the second power supply device and converts the voltage of the second power supply device for supplying driving force to the rotary electric machine through the inverter, an anomaly detecting means 7 that detects any internal anomaly in the voltage conversion device or the second power supply device and generates an anomaly signal, switching means 6, 5a that connect and disconnect the voltage conversion device and the power supply line to and from each other, and a controller 8 that, on receiving an anomaly signal from the anomaly detecting means, opens the switching means to separate the voltage conversion device and the second power supply device from the power supply line.
