Abstract:
PCT No. PCT/DE97/00605 Sec. 371 Date Jan. 12, 1998 Sec. 102(e) Date Jan. 12, 1998 PCT Filed Mar. 25, 1997 PCT Pub. No. WO98/02333 PCT Pub. Date Jan. 22, 1998A device for supplying voltage in a motor vehicle is described in which there is at least one generator that can furnish an generator-speed-dependent output voltage without voltage regulation. The at least one generator is preferably a three-phase alternator with a plurality of stator windings whose electrical connections are switchable at predetermined generator speeds by a control unit to provide the generator-speed dependent output voltage. In a following power control unit, this generator speed-dependent voltage is rectified by means of at least one controlled rectifier bridge and via assigned voltage converters is converted into a plurality of directly voltages of different magnitude. These direct voltages are supplied to the individual on-board electrical system components via electronic vehicle body power control system units. By optimal-efficiency triggering of the controlled rectifier bridges and additional safety and/or emergency provisions, the functional capability and power capability of the voltage supply unit are assured.
