Abstract
A charging circuit detects a battery voltage Vp and a charging voltage of a main condenser. When a charge of the condenser is instructed, if the battery voltage is smaller than prescribed value Vpo, the charge is performed in a single control mode. And then, when the charging voltage of the main condenser is larger than a prescribed value Vco, the mode is changed to a push-pull control mode from the single control mode. When the charge of the condenser is instructed, if the battery voltage is larger than prescribed value Vpo, the charge is performed in a push-poll control mode independent of the charging voltage.
