Abstract
The aim is to be able easily and without an additional transmitter to transmit information on the generated operating current from the secondary to the primary side of the transformer (Tr). Power is briefly returned from the secondary side to the transformer (Tr) in the form of a back-load current (iT2) via a switch (T2) on the secondary side. The setting (Ur) for the control is obtained from the voltage (U2) generated by the back-load current on the primary side. Circuit component especially for a television receiver or a video recorder.
