ABSTRACT:
The power loss developed in a semiconductor switch during turning on the current flowing from a DC source through a main inductor is reduced by connecting in series between the switch and the main inductor the series combination of a diode and a further inductor, with the diode being poled to pass current from the switch to the main inductor. The parallel combination of a further capacitor and a further diode is connected between a tapping on said further inductor and the junction of said series combination with the semiconductor switch. To reduce the power loss during turning off the current there is connected between the junction of the semiconductor switch and the inductor two parallelled series combinations of diode and capacitor with the elements in opposite order in the branches and the diodes poled in the same direction, the junctions of the capacitors and diodes in the two series combinations being connected through a series diode-inductor combination. The series combination of semiconductor switch and inductor may be one half of a push-pull inverter circuit.
