Abstract

Abstract: According to the switch capacitor network working characteristics of discharging in series, charging in parallel, a high ratio bidirectional DC-DC converter based on switch capacitor network was proposed. In order to improve the converter's ability of resist input voltage disturbance and dynamic response speed, an improved method was focused on which combined the advantage of one-cycle control and the output voltage feedback compensation control, which could realize inhibition the input voltage perturbation in one cycle and improve the converter's resistance ability of load disturbance. The operating principle and control characteristics of the new converter were analyzed. The improved one-cycle method was used into the converter to research the input voltage, load and given voltage change cases. Simulation and experiment results show that the new converter has higher transformation ability and the improved one-cycle control improves the converter's resistance ability of load disturbance and has a good robust.
