And the resulted AC current on the DC side will have the similar frequency shift when transfers to the stator of the generator.

直流侧电流扰动反映到交流定子侧，也将发生频率偏移。

So harmonic current should be suppressed firstly rather than harmonic voltage. The harmonic characteristic on the network side and the ac side of medium-frequency power supply is analyzed.

分析了电网侧和中频电源交流侧的谐波特性，并针对中频电源提出了几种谐波抑制措施。
