Control circuit for controlling a switched converter generating an output voltage which is independent of variations of the input voltage. For this purpose, a forward control is used with a sawtooth voltage of which both the variation during the pulse duration of the pulses applied to the switch of the converter and the slope are linear functions of the input voltage and of an adjusting voltage. The output voltage is proportional to the adjusting voltage. This can be derived from the output voltage by means of a feedback coupling. |
