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。

This paper presents a novel concept for system integration at system level, which is to select output impedance of source converter and input impedance of load converter as objects of standardization.

该文提出一种新颖的系统集成的观点，即从系统级的高度将分布式供电系统中的源变换器的输出阻抗和负载变换器的输入阻抗作为标准化研究的对象。

Such a theoretical device would have a zero ohm output impedance in series with the source.

这种理论的设备将有一个与源系列零欧姆的输出阻抗。
