The invention relates to smoothing a consumer electrical circuit supplied by a controllable current sink connected in parallel to the consumer. For this purpose, measuring voltage proportional to a load current supplied to the consumer is derived therefrom. A pick value measuring device makes it possible to determine a maximum value thereof. The difference between the maximum value and measuring voltage makes it possible to control the voltage-controlled current sink in such a way that the sum of a compensation current supplied by the current sink and the load current which runs by the consumer is substantially constant.

Device for smoothing the load current supplied to a load

The invention relates to an arrangement for controlling the output power of a high-frequency transmitter. The control power of the transmitter output stage is controlled according to a correcting variable (R) and by means of an actuator, whereby said variable is obtained by comparing the output power to a desired value (S). An I./Q modulator (M) is used as actuator.
