摘要

针对升压变换器的开关损耗和动态响应问题，提出了一种基于移相全桥(PSFB)的自级联升压变换器。该拓扑是通过串联PSFB转换器的输出和输入来实现的。零电压开关(ZVS)用于降低开关损耗。通过对小信号模型的分析，说明了SCB变换器的理想动态响应。利用Matlab/Simulink软件搭建了原型电路。通过仿真和实验波形数据，验证了所提拓扑的有效性。

Self-cascade boost converter based on the phase-shift full-bridge circuit

Contraposing the problem of switching loss and dynamic response of boost converter, a self-cascaded boost (SCB) converter based on phase-shifted Full-Bridge (PSFB) is proposed. The topology is realized by connecting the PSFB converter output in series with its input. The zero-voltage-switching (ZVS) is used to reduce switching losses. By analyzing the small signal model, the perfect dynamic response of the SCB converter is illustrated. Matlab/Simulink software is used and a prototype circuit is built. According to simulation and experimental waveform data, the effectiveness of the proposed topology is verified.
