最常用的电子系统包括一个传统的单相全桥整流器和输入式滤波电容。这类电路从电源线中获取电流峰值，产生高的谐波。高值的总和谐失真（ＴＨＤ）和低功率因素（ＰＦ）减弱了最大功率的使用，并降低了电力供应网络的效率。为达到欧洲标准（ＥＮ６１０００－３－２），即对于１
The most common electronic systems include a traditional single-phase full-bridge rectifier and input filter capacitor. This type of circuit draws current peaks from the power lines, producing high harmonics. High total harmonic distortion (THD) and low power factor (PF) reduce the use of maximum power and reduce the efficiency of the electricity supply network. To meet the European standard (EN61000-3-2), ie for 1
