Abstract

This paper presents a bi-directional bridge modular switched-capacitor-based resonant DC-DC converter, and the corresponding phase-shift control strategy is proposed for it. Under this control method, bi-directional flow of energy can be realized between the high and low voltage sides. Meanwhile, the output voltage regulation can be achieved 0.15–0.44 times voltage conversion ratio at the step-down mode and above 2.5 times at the step-up mode. In additional, zero-voltage switching (ZVS) operation can be obtained for switches, which improves the system efficiency further. Meanwhile, the working principle of the converter is discussed and the operation parameters are calculated in detail in the converter's optimal working condition. At last, the prototype of proposed converter was built and the experimental results has verified the feasibility and the high efficiency of the proposed converter.
