Abstract
In order to prevent discharge of the battery () of a motor vehicle during operation of heavy current consumption devices, a circuit configuration is to be prepared which comprises essentially a rotary current generator (), a vehicle battery (), one or more current consuming devices (), and a controllable voltage converter (). The voltage converter () supplies an output voltage which varies as a function of the control signal of a control unit () of the current generator () and which supplies the current consuming device (). In the event of overloading of the rotary current generator () the output voltage of the voltage converter () is lowered in order to reduce the current consumption of the device () and prevent overloading of the rotary current generator () and discharge of the vehicle battery ().
