This topology can share a bidirectional power flow between the input and output ports. Also, by adjusting the duty cycles of the power switches, it can operate in boost and buck mode. The suggested topology has three ports, a low voltage side, a high voltage side, and one auxiliary port. In the structure of the proposed converter only three power switches and two inductors are used. Therefore, other advantages of this converter are low component count and high efficiency. To illustrate the performance and effectiveness of the recommended topology, technical statues and steady-state survey, design procedure, efficiency calculation, and comparison assessment are provided. Finally, to verify the theoretical investigation, an experimental prototype with capability to operate in boost and buck operation, with 170 W rated power in boost mode and 90 W in buck mode, with 50 kHz switching frequency is built and its results are presented.}, keywords = {Bidirectional DC-DC Converter,high voltage gain,Low voltage stress,Low component count}, url = {https://www.jemat.org/article_161741.html}, eprint = {https://www.jemat.org/article_161741_dd0422297a7176983acadff0ba77e586.pdf} }
