In this paper a non-isolated high gain DC-DC converter which is preferred for photovoltaic (PV) applications is proposed. This converter uses hybrid switched inductor technique to enhance its overall voltage gain. The inductors of the gain extension network are all charged together in parallel and get discharged simultaneously in series to obtain the high voltage gain (>10). Resultantly, the voltage stress experienced by the switches of the proposed converter are reduced to 55% of the desired output voltage. An experimental prototype version of the proposed converter yields the rated voltage gain of 10.8 and delivers 21OW at a maximum efficiency of 94.45% when excited from an input voltage of 35 V. Further, the operating range of the converter is demonstrated by experimental results which are obtained for an output power ranging from 90% to 95% of rated power. © 2019 IEEE.
