Abstract
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. Rectifying elementsof 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 elementin FIG.may be replaced by self-conducting MOS field effect transistors (depletion mode MOSFET). The p-channel JFET of the exemplary embodiment according to FIG.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.
