摘要/Abstract

摘要： 针对单管正激SWISS整流器高频开关管电压应力大、移相全桥SWISS整流器有直通风险等问题,基于传统SWISS整流器进行设计,提出一种双管正激SWISS整流器拓扑。将双管正激变换器和SWISS整流器进行结合,实现了SWISS整流器的电气隔离,减小了高频开关管的电压应力;同时,输出电路的每个桥臂由一个二极管和一个开关管串联组成,提高了整流器的可靠性。对双管正激SWISS整流器的工作原理和开关管的电压应力进行详细分析,并针对扇区边界处输入电流振荡问题,设计一种两级滤波器用于抑制电流振荡。最后在仿真平台验证了该整流器拓扑的可行性和两级滤波器的有效性。

Abstract: In order to solve the problems of high voltage stress in high-frequency switching tubes of SWISS-forward rectifier and the straight-through risk of SWISS phase-shift full-bridge rectifier, a dual-transistor forward SWISS rectifier topology is proposed in this paper. The fusion of the dual-transistor forward converter and SWISS rectifier not only provides direct galvanic isolation for the SWISS rectifier but also reduces the voltage stress of the high-frequency switching transistor. At the same time, each bridge arm of the output circuit is composed of a diode and a switch in series, which ensures the reliability of the rectifier. The working principle of the dual-transistor forward SWISS rectifier and the voltage stress of the switching tube are analyzed in detail, and a two-stage filter is designed to suppress the current oscillation in order to solve the problem of input current distortion at the sector boundary. Finally, the feasibility of the rectifier topology and the effectiveness of the control method are verified on the simulation platform.
