摘要： 基于开关电容网络串联放电、并联充电工作特点,提出一种实现输入输出电压大变比的双向开关电容网络DC-DC变换器。针对变换器抗输入扰动抑制能力差和动态响应速度慢等问题,提出采用单周期控制结合输出电压反馈补偿控制方法,实现在一个周期内有效抑制输入电压扰动并提高变换器抗负载扰动能力。分析了双向开关电容网络DC-DC变换器的工作原理和控制特性,并对所提电路及其在输入电压、负载以及给定等参数变化时的状态进行实验和仿真研究。结果表明：变换器具有较强的升降压能力;改进单周期控制变换器具有良好的抗扰动能力和更强的鲁棒性。

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.

Key words: switch capacitor network, high gain, bidirectional DC/DC converter, improved one-cycle control
