The common and differential mode voltage produced by the PWM inverter can generate large common and differential current in the motor driving system.
由三相pwm逆变器产生的共模和差模电压可以在电机驱动中产生足够大的共模和差模电流。
In either case, that voltage is unwanted, and it is the job of the measurement SYSTEM to REJECT it, while responding to the differential-mode voltage.
另外的原因是该电压没有用，是测量系统工作时所抑制的，而只响应差模电压。
In applications such as motor CONTROL, POWER-supply current monitoring, and BATTERY cell-voltage monitoring, a small differential voltage must be sensed in the presence of a high common-mode voltage.
对象马达控制、电源电流监视、电池电压监视之类的应用，必须把一个存在于高共模电压的小差分电压提取出来。
