This paper presents a new boost dc-dc converter with high efficiency by using a partial resonant circuit. The switching devices in the proposed converter are operated by a soft-switching technique (ZCS; zero current switching, or ZVS; zero voltage switching) of a new partial resonant circuit. The partial resonant circuit makes use of a step-up inductor and a loss-less snubber capacitor. The switching control technique is simplified for the switches to drive in constant switching frequency with PWM (pulse width modulation). The results are that the switching power loss is very low and the system efficiency is high.
