一种无源无损钳位的新型单级PFC变换器
A novel single-stage PFC converter with non-dissipative clamping
摘要
Abstract
A new single-stage PFC converter was pointed out,which adopted DPT (direct power transfer) to improve the conversion efficiency and reduce the capacitor voltage,and introduced LCD non-dissipative clamping circuit to absorb the leakage energy and clamp the switching voltage.The experimental results show that it can absorb the leakage energy and make the conversion efficiency improve about 1.4%,at the case of maintaining the capacitor voltage less than 300 V and switching voltage lower than 450 V.The effectiveness of this structure at solving the current problems encountered by the single-stage PFC circuit was proved.关键词
