    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.

    摘要翻译： 构成车载交流发电机的全波整流器的整流元件由肖特基势垒二极管构成。 肖特基势垒二极管一方面具有由于由于浪涌电压而产生的大雪崩击穿电流导致的发热而导致整流特性恶化的缺点，结果是施加反向电压时发生的漏电流增加。 然而，根据本发明，由于浪涌电压被与肖特基势垒二极管并联连接的电压调节二极管吸收，所以在施加了浪涌电压时，电压调节二极管被分解。 因此，不会将超过电压调节二极管的击穿电压的反向电压施加到肖特基势垒二极管。 因此，不会由于浪涌电压超过其击穿电压而流过的电流在肖特基势垒二极管中流动。

    摘要： In an on-vehicle alternator, both the magnetic flux variation frequency and maximum flux density are decreased sufficiently to thereby decrease the internal iron loss and thereby realize an increase in the current generation efficiency. The on-vehicle alternator comprises a rotor wherein magnetic pole cores that are polarized by a rotor coil to alternately different polarities are circumferentially disposed on the outer periphery thereof at prescribed equi-angular intervals. A permanent magnet which is embedded within a resin-made retainer body is provided between the magnetic pole cores and has side faces, as viewed circumferentially, which are polarized respectively to the same polarities as those of adjacent respective magnetic pole cores to thereby vary the magnetic flux quantity directed toward stator coils so as to exhibit a circumferential gentle curve. A rectifier is constructed using SiC-MOS transistors so that it is conductive and operative to thereby charge a battery with the current developed in the stator coils only when the alternating current voltages generated in the stator coils have become higher than the battery voltage.
