In power converters, unbalances generate undesirable DC ripple and non characteristical harmonics in the AC side.

在电力变换器中，不平衡会产生不希望的直流波动以及交流侧无特征的谐波。

Because the clamp effect of DC voltage source, AC side output the rectangular wave voltage waveform, and it has nothing to do with the load impedance Angle.

由于直流电压源的钳位作用，交流侧输出电压波形为矩形波，并且与负载阻抗角无关。

During the so-called braking of the motor, the power flows from the ac side to the dc side of the switch-mode converter and it operates in a rectifier mode.

在所谓制动阶段，功率从开关型变流器的交流侧流向直流侧；此时变流器相当于一个整流器。

The absence of Pienaar, whose Spurs side recently knocked AC Milan out of the Champions League, would be a blow for Mosimane, who would need to name another captain just days after axing Mokoena.
