Abstract
In this paper, a new topology for an isolated DC-DC converter that can be used for electric vehicle applications is presented in a dual bridge structure, having just one switch, two capacitors, and an inductor each in the front-end and back-end H-bridges, along with a high-frequency transformer (HFT) for isolation of the bridges. Simulations were done in MATLAB/Simulink to verify the structure and working of the converter. The converter showed very high efficiency of more than 98% in isolation mode, buck mode, and boost mode operations, with very low voltage and current ripple values of less than 5%. Finally, a comparison study with a recent similar half bridge converter topology is also done to discuss the benefits of the proposed topology.
