Abstract
It is already known in the art to connect a network consisting of a capacitor, a resistor and a diode to a transformer (Tr) to limit voltage peaks. The aim of the invention is to decrease the relatively high losses of about 10 % in the resistor. This network is replaced by a capacitor (C2), and located on the secondary-winding side, in parallel with the diode (D1) which generates the operating voltage, is a switch (T2) which, when the charging current (iD) for the charging capacitor (C1) has decayed away, generates a current (iT2) from the charging capacitor (C1) back to the secondary winding (2). Particular applications of the circuit of the invention are in television receivers and video recorders.
