Abstract
A field-effect transistor incorporates a diode which is disposed between a battery power source and an inverter. A rush-current suppressive starting circuit is provided in a stage anterior to the field-effect transistor. The transistor is shifted to its conducting state while the on-resistance of the transistor is gradually lowered to thereby limit a charging current to a power smoothing capacitor. In an off-state of a main switch, a charge stored in the current smoothing capacitor is released therefrom via a stabilized power circuit and a controller which is a power load to the circuit.
