A New Energy Recovery Snubber for Boost Converter

부스트 컨버터용 새로운 에너지재생 스너버

The main switch of high-frequency boost converter may be failed because the high switching current or voltage can damage this switch. The high switching stress can be reduced by snubber circuit. In this paper, a new passive snubber circuit which can recover trapped snubber energy without added control is proposed for boost converter. The control of boost converter with proposed snubber is the same as the conventional one. In addition, the energy recovery circuit can be implemented with a few passive components. The analysis for proposed circuit is presented, and the validity of the circuit is verified through simulation and experiment.
