Soft Switching Boost Converter for Photovoltaic System with Maximum Power Point Tracking

MPPT 기능을 갖는 태양광 발전용 소프트 스위치 부스트 컨버터

In this paper a high efficiency soft switching boost converter is proposed for photovoltaic system. Using some resonant components, the circuit can be achieved the soft switching capability. Each of the switches in the proposed circuit performs ZV (Zero Voltage) or ZC (Zero Current) switching. Thus, the high efficiency characteristic can also be obtained, and then the size of the total system can be reduced. The operational modes of the verifying the effectiveness of the proposed circuit. As a matter of course, we will present the simulation results in this paper.
