Abstract	The authors present a novel topology for a single-phase PWM (pulse width modulation) inverter with sinusoidal output voltage at 50 Hz. The inverter is composed of power MOSFETs, fast recovery rectifying diodes, ferrite core transformers, and compact resonant filters tuned at 25 kHz switching frequency. It has high power-to-weight ratio, low total harmonic distortion, and good output voltage regulation for both input voltage and load current variations. The inverter is capable of operating at wide range of V/f ratios of the output voltage. The inverter can be used as a square wave inverter by giving a DC voltage as the modulating signal and commutating the relevant set of switches at the desired frequency. Inverter operation and the method of selecting power stage components are described, along with experimental results.
