In this paper, a novel dual-input high step DC-DC converter is developed. The structure of proposed converter consists of one unidirectional and one bidirectional port. The bidirectional port is connected to a battery for energy balancing purpose. That is, the battery stores extra produced energy and/or releases stored energy in situations where there is a lack of energy. On the other hand, the bidirectional port is employed as the main power source. The high step-up output voltage gain of the proposed converter makes it suitable for renewable energy applications where the output voltage is low. The proposed structure is superior over the previously proposed ones in terms of the number of components, energy interaction, simple configuration, and flexibility. The experimental results obtained in three different modes (i.e., without battery, with battery charging, and with battery discharging) are presented to verify the theoretical analysis and the performance of the proposed converter.
