ABSTRACT:
A power supply circuit comprises a main transformer having a primary winding and a secondary winding, a series resonance circuit coupled to the primary winding of the main transformer, and a switching circuit for alternately supplying DC power to the series resonance circuit and discharging the energy stored therein. A current protection circuit controls the switching circuit in dependence upon the current in the switching circuit and a voltage protection circuit controls the switching circuit in dependence upon the voltage of the secondary winding of the main transformer.
