摘要：
Rectifying elements that constitute a full-wave rectifier of an on-vehicle alternator are constituted by Schottky barrier diodes. The Schottky barrier diode has on one hand the drawback that rectifying characteristics thereof deteriorate due to the heat generation resulting from large avalanche breakdown current that is produced due to surge voltage, with the result that leakage current that occurs when reverse voltage is applied increases. However, according to the present invention, since the surge voltage is absorbed by a voltage regulation diode connected in parallel with the Schottky barrier diode, the voltage regulation diode is broken down when surge voltage has been applied. Accordingly, it does not happen that reverse voltage that exceeds the breakdown voltage of the voltage regulation diode is applied to the Schottky barrier diode. Therefore, it does not happen that the current due to surge voltage exceeding the breakdown voltage thereof flows in the Schottky barrier diode.
