Abstract
A pair of diodes, which has an input terminal connected with a neutral point of a Y-connected output winding of an alternating current generator, is provided in addition to a full-wave bridge rectifier connected across a battery. A field winding of the alternating current generator is supplied with filed current from the battery or the full-wave bridge rectifier and further from the pair of diodes which are energized by the voltage appearing at the neutral point. The field current supply from the pair of diodes is not limited by a voltage regulator for controlling the output voltage of the generator, whereby a large increase of output power of the generator can be obtained.
