Abstract

The present invention relates to a method and apparatus for reducing voltage sags in the battery supply lines of the circuit arrangement which is used to regulate or control the current input of a consumer in an automotive vehicle, wherein the consumer current is regulated or controlled by pulse-width modulation (PWM) and a controllable switch is used. To this end, a circuit is used which influences the edges of a pulse-width modulated signal, and a signal representative of the rate of change in the current in the battery supply lines to the consumer is produced. This signal is fed back to the input signal by way of a capacitor.
