Abstract

A high frequency inverter circuit comprises two transistors 1, 7 and a series resonant circuit comprising a capacitance 15, 16 and an inductance 14. The transistors 1, 7 are connected in series across a D.C. source 25 and the resonant circuit is linked with the series connection point between the two transistors 1, 7 for driving a load 26 which is connected across the capacitance 15, 16 in order to utilize high voltage induced on the capacitance 15, 16 by switching the transistors 1, 7 alternately in synchronisation with the natural frequency of the resonant circuit. The magnetization of the current transformer 13 may be controlled by adjusting the turns ratio of the windings or the values of the base drive resistors (3, 5, 9, 11) in order to reduce power losses due to both transistors (1, 7) being conductive simultaneously. Additional transistors (2, 8) are also provided to improve switching.
