一种用于低频运行模块化多电平变换器的复合互感充电通道电容电压波动抑制方法

The voltage fluctuation problem would be produced in the submodule capacitor when the modular multilevel converter (MMC) is operating at the low-frequency stage, which will seriously affect the low speed and starting up performance of the variable speed motor load system. A capacitor voltage fluctuation suppression method is proposed in this article by employing the compound mutual inductance char...
