摘要
En 中文
This letter suggests a dc-dc converter with ultra-high voltage gain based on Y-source magnetically coupled network for interfacing renewable resources application. Utilizing the characteristic of Y-source network, the converter can achieve flexible adjustment of voltage gain and high voltage conversion ratio at small turns ratio of coupled inductor. On the basis of Y-source network, it also features continuous input current, lower voltage stress of switch and output diode, and wider control range of duty cycle. At the output side, a pumping capacitor cell enhances boosting capability with effect. The theoretical operation principle of the converter is analyzed thoroughly, including the case of considering the influence of leakage inductor. Moreover, the performance analysis is presented in detailed. A 200-W experimental prototype was constructed and the validity of proposed converter was verified.
