ABSTRACT:
There is provided a switching circuit (50) comprising: a transformer (TR1) including at least one winding (P1, S1, S2); a switching device (FET1) coupled between a source of power (60) and the transformer (TR), the switching device (FETI) being coupled to a driving circuits (100) for periodically driving the switching devices (FET1) into conduction to transfer power from the source (60) to the inductive component (TRi). The circuit (50) further includes: a first monitoring arrangement (115) for determining a measure of a magnetizing current present in the transformer (TR1); a second monitoring arrangement for deriving a measure of hard switching occurring in the switching devices (FETI); and a signal processing arrangement (140, 150, 160, 170, 175) for generating a measure of reflected power being transferred through the transformer (TRI) from the measure of the magnetizing current and the measure of hard switching.
