从图3 - 12可以看出,共模电流(ICM)是从电源线经过电源变压器通过电容耦合(CCOUPLING)而产生的。
As shown in Figure 3-12, common - mode current (ICM) is caused by capacitive coupling (CCOUPLING) from the power line through the power transformer.
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。
The common and differential mode voltage produced by the PWM inverter can generate large common and differential current in the motor driving system.
可能出现的共模电流(ICM)从电压表的输入低端流到仪器的机箱公共端,经过大地再流到电压源的地。
Any common-mode current (ICM) that may be present flows from the voltmeter input lo to instrument chassis common, through earth ground to voltage source ground.
