Power supply circuit for motor vehicles
First Claim
1. A motor vehicle power supply circuit with a plurality of power supply components, comprising a motor vehicle power supply voltage including a battery;
- a starter/generator;
a DC voltage intermediate circuit having an increased voltage relative to the motor vehicle power supply voltage;
a bidirectional converter, said battery being connected with said starter/generator through said DC voltage intermediate circuit and said bidirectional converter;
a number of consumers;
mains connected with said starter/generator through said bidirectional converter and also connected with said consumers; and
a control device connected with said converter so that said consumers are subjected to different voltages via said control device, said consumers being located between said battery and mains.

Abstract
A novel vehicle power supply system is suggested which receives its voltage supply from a starter/generator which can be used as a generator in normal operation and as a starter when starting, wherein the starter/generator is connected with a 24 volt ring mains as well as with a 24 volt battery via a pulse inverter and a 300 volt DC intermediate circuit and a bidirectional converter. Additional consumers can be supplied with higher voltages than 24 volts and electric control devices can be supplied with voltage, possible via additional converters, from the bidirectional push-pull converter and the 300 volt DC intermediate network. In addition, this vehicle power supply system contains a plug receptacle with a 220 volt 50 Hz voltage.
