提出了一种可适用于多谐振变换器的新型开关吸收电路,并将其应用于降压型和正向型变换器。通过降压型变换器的理论分析和实验,以及正向型变换器的实验,结果都表明变换器的开关电压应力大大降低,电流应力也得到降低,从而提高了变换器的效率。
A novel switch snubber circuit suitable for multi-resonant converters is proposed and applied to buck and forward converters. Through the theoretical analysis and experiment of the buck converter and the experiment of the forward converter, the results show that the switching voltage stress of the converter is greatly reduced and the current stress is also reduced, thereby improving the efficiency of the converter.
