    • A generator, for example a three-phase generator including an associated rectifier system, is used, for example for the electrical voltage supply of a motor vehicle. The AC voltage produced by the generator is rectified by the rectifier system having a plurality of rectifying elements 2, 7. Rectifying elements 2 of the rectifier have a plurality of series connections of a self-conducting n-channel JFET and a self-conducting p-channel JFET, the gate terminals being connected to the outer source or drain terminals of the other transistor. Alternatively, the self-conducting JFETS of the rectifying element 2 in FIG. 1 may be replaced by self-conducting MOS field effect transistors (depletion mode MOSFET). The p-channel JFET of the exemplary embodiment according to FIG. 1 is replaced by a self-conducting p-channel MOSFET and the n-channel JFET is replaced by a self-conducting n-channel MOSFET. Furthermore, the gate terminals are connected to the diametrically opposed outer terminals.
    • 使用发电机,例如包括相关联的整流器系统的三相发电机,例如用于机动车辆的电压供应。 由发电机产生的交流电压由具有多个整流元件2,7的整流系统整流。整流器的整流元件2具有多个串联连接的自导通n沟道JFET和自导电p 通道JFET,栅极端子连接到另一个晶体管的外部源极或漏极端子。 或者,图1中的整流元件2的自导电JFETS。 1可以由自导MOS场效应晶体管(耗尽型MOSFET)代替。 根据图1的示例性实施例的p沟道JFET 1被自导电p沟道MOSFET替代,并且n沟道JFET被自导n沟道MOSFET替代。 此外,栅极端子连接到直径相对的外部端子。
