ABSTRACT:
In a power supply apparatus for a vehicle, an inverter circuit inputs a voltage from a first battery unit through switches. A smoothing condenser is provided between the first battery unit and the inverter circuit in parallel. A DC-DC converter is provided between the smoothing condenser and a second battery unit to voltage-convert electric energy stored in the first battery unit or the smoothing condenser to supply to the second battery unit, and to voltage-convert electric energy stored in the second battery unit to supply to the smoothing condenser. An electronic control unit controls the DC-DC converter before starting power supply to the inverter circuit, such that the switches are closed after the smoothing condenser is charged to a voltage within a predetermined permission voltage range from the voltage of the first battery unit.
