摘要

本文提出了一种新型的单开关辅助谐振变换器,该变换器可以在没有辅助开关的情况下以软开关方式工作。在所提出的变换器电路中,谐振电路的电容作为无损缓冲器,可以降低功率半导体器件上的开关损耗、开关应力和电磁干扰噪声。此外,它们还能够进行传统的PWM控制。给出了工作原理、仿真结果、实验结果和其他应用实例来验证分析结果。

Single-switch auxiliary resonant converters
This paper presents new single-switch auxiliary resonant converters which can operate in a soft-switching way without auxiliary switches. In the proposed converter circuits, the capacitors of the resonant circuit act as lossless snubbers which can be expected to reduce the switching losses, the switching stresses and EMI noise on the power semiconductor device. Moreover they are also capable of conventional PWM control. The principle of operation, simulated results, experimental results and other applications are presented to verify the analysis.
