Abstract

In this paper, a novel proposal of the utility-interactive three-phase soft commutation sinewave PWM power conditioner with an auxiliary active resonant DC-link snubber is developed for the fuel cell and the solar power generation systems. The prototype of this power conditioner consists of a PWM boost chopper cascaded three-phase power conditioner, a single two-switch auxiliary resonant DC-link snubber with two electrolytic capacitors incorporating into one leg of three-phase V-connection inverter and the three-phase AC power source. The proposed cost-effective utility-interactive power conditioner is implemented to use a unique design and control system of a high-frequency soft switching sinewave PWM scheme for all system switches. The operating performances of 10 kW experimental setup including the waveform quality, EMI / RFI noises and the actual efficiency characteristics of the proposed power conditioner are demonstrated on the basis of the measured data
