Abstract

A DC to AC sinewave converter having an FET with its gate terminal coupled to a switching signal which turns the FET on and off. A pair of parallel, oppositely conductive diodes couples the drain terminal of the FET to a resonant circuit that is responsive to a source of DC voltage. A clamping diode is connected between the parallel diodes and the source terminal of the FET for preventing the drain and source terminals from being reverse biased.
