A High Gain DC/DC Converter With Zero Input Current Ripple Based on Magnetic Integration
摘要
Abstract
A high gain DC converter with zero input current ripple based on magnetic integration is proposed in order to solve the problems of low output power of PV power module and large input current ripple of DC/DC converter.Based on the improved Sepic circuit structure,the input inductor and transformer are magnetically integrated so that the converter can actualize high gain and zero input current ripple with only one magnetic element.This paper describes the working principle of the proposed converter,the zero ripple property of the input current,the voltage gain,and the stress property of the switching device.the key parameters are designed,and the magnetic integration design scheme is elaborated in detail.In order to prove the correctness of the theoretical analysis,a 143 W,56 V/380 V prototype is established.关键词
