A High-Gain Zero-Current Ripple Charge-Pumped Bidirectional DC-DC Converter

This paper proposes a non-isolated bidirectional DC/DC converter topology to meet the need for high-gain DC/DC converters for applications such as battery storage systems, photovoltaic generators, and fuel cells. The converter consists of an active switched induction (ASL) element, a zero-current ripple element and a charge pumping element. This new topology combines the traditional active switched inductor with a charge pump cell, and it has the advantages of high voltage gain, wide gain range, power element stress, and input/output common ground. In this paper, the operation principle of this converter is analyzed in depth, and simulation experiments of this converter topology are carried out using PSIM simulation software, and the results demonstrate the validity of the theoretical analysis of the proposed topology.
