Utility-Interactive Four-Switch Three-Phase Soft-Switching Inverter with Single Resonant DC-Link Snubber and Boost Chopper

다국어 초록 (Multilingual Abstract)

In this paper, a novel proposal for a utility-interactive three-phase soft commutation sinewave PWM power conditioner with an auxiliary active resonant DC-link snubber is developed for fuel cell and 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 incorporated into one leg of a three-phase V-connection inverter and a three-phase AC power source. The proposed cost-effective utility-interactive power conditioner implements a unique design and control system with a high-frequency soft switching sinewave PWM scheme for all system switches. The operating performance of the 10 kW experimental setup including waveform quality, EMI / RFI noises and actual efficiency characteristics of the proposed power conditioner are demonstrated on the basis of the measured data.
