A circuit arrangement regulates the power drawn from a supply network by at least one load 50 with linear and/or non-linear current-voltage characteristics. It has a controlled switch 51 which is connected in series, and preferably a sensor circuit 54 in series and/or parallel, with the load. A regulating circuit 55 is arranged between the sensor circuit 54 and the controllable switch 51. In the input circuit of the regulating circuit 55, the actual value for the operational state of the load 50 is formed by a mean value formation of the current of the load 50. The output of a mean value former 57 forms one input quantity of the regulating circuit 55 and the output of the sensor circuit 54, determining the momentary value of the load current, is connected to the input of the mean value former 57. Thus a quantity corresponding to the mean value of the load current forms one input of circuit 55, and another input of the circuit 55 is a desired value linked in phase with the supply. <IMAGE> |
