Nowadays, high power medium voltage drives are becoming more important in industry to reduce energy losses and increase productivities for the operating of pumps, fans, traction motors, etc. These high power drives typically suffer harmonics, resonance and common mode voltage during their operations, which will introduce additional stress and losses on the drives and the motors. Traditional approach to deal with these problems is through passive filtering and damping which increase the cost, size and weight of a drive system.

如今，大功率中压驱动器在工业中变得越来越重要，以减少能量损失并提高泵，风扇，牵引电机等的运行效率。这些高功率驱动器在运行过程中通常会受到谐波、谐振和共模电压的影响，这将给驱动器和电机带来额外的应力和损耗。处理这些问题的传统方法是通过无源滤波和阻尼，这会增加驱动系统的成本、尺寸和重量。
