Abstract

PURPOSE:To prevent the production of heat and harmonic wave output at switching time by providing a resonator circuit for operating in E class operation a switching element between a DC power source and a transmission transformer. CONSTITUTION:There is provided a resonator circuit becoming resonance frequency corresponding to the frequency of a switching signal SG11 at the values of inductors L11, L12 and capacitors C11, C12 between the DC power source E11 and the transmission transformer T11. This, the switching transistor Q11 operates in E class to become ON when the voltage between the emitter and the collector is near zero and OFF when the voltage between the emitter and the collector is high. As a result, it can prevent the heat of the switching transistor, can form the output of the transformer T11 in the vicinity of the sine wave, can reduce the harmonic wave component, and can prevent the induction fault beforehand.
