چکیده
This paper introduces a new soft switching boost converter with passive snubber. In the proposed converter, the main switch turns on under zero current switching (ZCS) and turns off under zero voltage switching (ZVS) without any additional voltage or current stresses. The main diode turns on under ZVS and turns off under ZCS. The proposed converter has features as low cost, simple control, low number of element and high power density. There is no additional voltage stress on any semiconductor power devices. In this study, the operating principle of the proposed converter is presented and its operation is verified for 200 W and 100 kHz model. KeywordsPassive Snubber Cell, Coupled Inductor, Zero-Voltage Transition, Zero-Current Transition, Soft Switching.
