ABSTRACT:
In a forward converter having at least one storage inductance, a clock switch connected in series with a winding of the at least one storage inductance, a control circuit for outputting a control signal as a function of the magnitude of an output voltage relative to a set reference voltage, and at least one MOS field effect transistor, MOSFET, which is operated inversely to the clock switch and, during ON periods of the clock switch, provides a free-running circuit via the storage inductance and a load connected at the output of the forward converter, a further transistor operating as an inverter is provided. The further transistor is connected to receive the control signal from the control circuit and is connected to the gate of the at least one MOSFET so that the at least one MOSFET receives the control signal for switching the clock switch via the further transistor as a voltage across the further transistor.
