ABSTRACT:
A power supply system for supplying electric energy to a rotary electric machine coupled to a rotatable shaft of a turbocharger for supercharging an engine includes a battery for supplying electric energy to the rotary electric machine, and a capacitor connected parallel to the battery through a switching control device. The capacitor is charged with electric energy from the battery at all times. When the engine needs to be revved up for quick acceleration, the switching control device is energized to supply electric energy stored in the capacitor, together with the electric power from the battery, to the rotary electric machine. Since the capacitor has a smaller internal resistance as compared with the battery, the capacitor can supply a large current to the rotary electric machine immediately after the accelerator pedal is deeply depressed for quick acceleration.
