本文提出了用输出电压为正弦、共模电压为零的滤波器对多电平逆变器驱动系统中共模电压进行无源补偿的方法。应用该解决方案的主要问题是CM扼流圈的磁饱和。已经提出了仿真和实验结果表明，磁饱和的问题变得不那么重要，在多电平逆变器驱动器，从而允许在这样的驱动器中的滤波器的电感元件的尺寸，重量和成本的减少。
In this paper the method of passive compensa- tion of a common mode (CM) voltage in a multilevel inverter drive system by means of the filter having sinusoidal output voltages and zero CM voltage has been presented. The main problem with the application of this solution is a magnetic saturation of the CM choke. There have been presented simu- lation and experimental results showing that the problem with magnetic saturation become less important in multilevel in- verter drives, thus permitting a reduction of size, weight and cost of inductive components of filters in such drives.
