Abstract	This paper is concerned with a novel proposal of the utility AC interactive three-phase soft commutation sinewave PWM power conditioner developed for solar photovoltaic power generation system and parallel processing UPS with new type battery and super capacitor energy storage devices. The prototype of this power conditioner is composed of two quadrant soft switching PWM chopper with step-up and step-down voltage operating modes, three-phase V-connection soft switching PWM inverter incorporating a single two-switch auxiliary resonant DC link snubber into one phase of three-phase bridge legs with divided capacitors, and the three-phase utility AC power source grid. The operating principle of the proposed power conversion conditioning circuit and system including some unique features and based upon high-frequency soft switching sinewave PWM scheme is described and discussed. The operating performances; waveform quality and actual efficiency of cost effective utility interactive power conversion conditioning and processing circuit treated here are evaluated and discussed on the basis of experimental data.
