A switched-boost DC/DC converter with high voltage gain and continuous input current

A new switched-boost DC/DC converter with high voltage gain is presented in this paper. Compared to other equivalent high voltage gain converters, the proposed converter utilizes less number of passive elements. Moreover, it uses two active switches with the same control signal and it has a shorter commutation paths, resulting in the lowest possible voltage spikes across these switches. In addition, the merit of having a continuous input current in the proposed converter makes it convenient to many applications like the renewable energy systems. The proposed converter is analyzed and compared among its counterparts from different perspectives. Finally, the introduced analysis is verified using simulation and experimental results, where a 200 W prototype is utilized.
