摘要
二本文论述了有源钳位正激变换器的原理与设计。利用有源钳位电路实现功率变压器对称磁复位,部分磁化能量用来对功率开关寄生电容放电到零,实现零电压开关。有源钳位技术增强了正激变换器性能。实验证实了理论分析的正确性。
The analysis and design of an active clamped forward converter is presented in this paper. By using an active clamped circuit,the power transformer is symmetrically magnetic reseted,and a part of magnetizing energy is used to discharge the parasitic capacitances of the power switch to zero in order to obtain zero voltage switch. Active clamped technique enhances forward converter performance and the theorical analysis is verified by the experimental result.
