摘要:
针对传统Boost功率因数校正(PFC)在低压输入时由于导通损耗大,效率偏低的问题,提出一种零电压转换(ZVT)无整流桥Boost PFC。对一个开关周期内各开关的通断情况,主要电压、电流变化情况等进行详细分析,结果表明主开关及辅助开关都实现了软开关,并且具有最小电压、电流应力,在此基础上研究软开关实现条件,最后制作一台用单周控制方法控制的ZVT无整流桥Boost PFC实验样机。实验结果表明,主开关实现了零电压开通、近似零电压关断,辅助开关实现了零电流开通、零电流关断,额定条件下功率因数在0.99以上,效率可达96%,验证了理论分析的正确性。
Abstract:
The conducting loss of the traditional Boost power factor correction(PFC) is high,which results in the low efficiency of it,especially when the input voltage is low.According to these above,a ZVT bridgeless Boost PFC is proposed.The on off status of the switches and the main voltages and currents in one switching period are analyzed in detail.The results have shown that the main switches and the auxiliary switch have realized soft switch,and the voltage and current stresses of them is minimized.Based on the...
