<p><P>PROBLEM TO BE SOLVED: To provide a power supply system for charging a battery even when an engine operates at a low speed. <P>SOLUTION: The power supply system has a three-phase AC generator in which phase circuits of three phases areΔ-connected or Y-connected; and a half-wave rectification type multiple voltage circuit for applying half-rectification to each line voltage of the three-phase AC generator and multiplying the voltage. The half-wave rectification type multiple voltage circuit includes a group of capacitors connected between line output terminals of theΔconnection or the Y connection of the three-phase AC generator and charged by the line output voltage; and a group of diodes each provided between an output end of one side of the half-wave rectification type multiple voltage circuit and one end of each phase circuit of the three-phase AC generator, and preventing each phase circuit of the three-phase AC generator from being short-circuited when the group of capacitors are charged by a reverse phase voltage of the three-phase AC generator. A voltage corresponding to a voltage obtained by adding the line voltage output of the three-phase AC generator to the charging voltage of the capacitor is supplied to the load. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
