Abstract :

In this article, a multi-input non-isolated converter topology with high gain is proposed for clean energy applications that require an energy storage system. The techniques of voltage multiplier cell and coupling inductor have been used to design the circuit, and by combining them, it is possible to use switches with low voltage stress and as a result, low conductivity. The charging performance of the energy storage system is explained and the structure and performance of the proposed converter are investigated for the design of a non-isolated multi-input converter with high voltage gain. The precise design method for the correct operation of the converter is presented and the simulation results of the converter performance are shown. Finally, in order to verify the accuracy of the results obtained from the simulation of the proposed converter, a laboratory sample has been made and a comparison has been made between the results.
