상용차를 위한 무시동 에어컨 압축기용 공진형 DC/DC 컨버터 개발

This study deals with a resonant converter of an anti-start air conditioner compressor for commercial vehicles. The anti-start air conditioner compressor must generally have a high current, high efficiency, a low volume, and a low weight. To reduce the switching losses and voltage and current stresses of the device, the anti-start air conditioner compressor applies the full-bridge L-C resonant converter topology. Hardware parameters are designed to have a wide voltage range, and the switching frequency range of the L-C resonant converter is determined. Simulation is implemented using PSIM and an experiment is performed to verify the proposed converter.
