Zusammenfassung:PCT No. PCT/EP96/05490 Sec. 371 Date Jul. 1, 1998 Sec. 102(e) Date Jul. 1, 1998 PCT Filed Dec. 7, 1996 PCT Pub. No. WO97/25771 PCT Pub. Date Jul. 17, 1997A new vehicle electrical system has a first lower voltage level and a second higher voltage level. The new vehicle electrical system comprises an ignition switch, a generator having an exciter circuit and a voltage controller, and a multi-chopper having several chopper stages. The voltage controller supplies energy to the exciter circuit via the ignition switch in order to adjust the first lower voltage level to a rated level of U1. The multi-chopper is connected between the battery and the generator, thereby adjusting the second higher voltage level to a rated level of U2 based on the number of chopper stages and their actuation.
