摘要
通过软开关改善DC/DC变换器的效率和电磁干扰(EMI)特性 ,是提高AC/DC变换器EMI性能的重要途径。通过对软开关单位功率因数AC/DC电路的拓扑研究、PSPICE仿真和电路实验 。
Soft switching techniques can improve DC/DC power converter's efficiency and reduce its EMI. The method is attractive to unity power factor AC/DC converter in the view of the EMC requirement for lower switching noise. A soft switched boost converter has been studied in topology analysis, PSPICE simulation and circuit experiment. The reduction effect of AC/DC converter EMI emission by using soft switching techniques and its limitation are investigated.
