du/dt滤波器连接与变频器输出端，

用于降低变频器输出的du/dt和吸收电机线路的反射电压。

功能和益处 Features and benefits

■降低IGBT输出的高dv/dt, 保护电机Complete protection of the motor from dv/dt and overvoltages

■抑制变频器输出的电磁干扰，消除了电机的电磁噪音Reduction of the acoustic noise of the motor

■延长传输距离至2倍标准长度（最大300米）  Extend motor length to 2X standard length. (300m max)

■降低电机涡流损耗Reduction of the additional magnetic losses and eddy current losses in the motor
