Abstract
Power generation by an alternator is controlled by switching a target charging voltage by a signal from an engine control unit so that engine-starting characteristics when the engine starts are prevented from deterioration due to the load of the alternator. The circuit initiates the generation by the alternator according to a gradual excitation control signal when the engine starts and makes the alternator generate according to a prohibit-power-generation signal after the completion of the starting.
