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。

And the waveform of the output pulse looks like rectangular. The pivotal component of the power supply is Frisbee Mechanism Spark Gap Switch, which is never seen in other power supply before.
