摘要：

A new soft-switching boost converter with simple-structure passive lossless snubber is proposed in this article. It shows various advantages as low cost, few auxiliary elements, and low-voltage stress on the switch. The passive snubber circuit consists of an inductor, two capacitors, and two diodes. It provides zero current switching (ZCS) turn-on and zero voltage switching (ZVS) turn-off for the switch. The main diode turns on under ZVS and turns off under zero-voltage ZCS, therefore, reverse recovery problem is solved. Also, total efficiency and conducted electromagnetic interference of the proposed converter compared to the conventional boost converters are improved. To prove it, 220 W prototypes are implemented. The experimental results along with the theoretical analysis confirm an increase of 3% in efficiency of the proposed converter.
