模块化多电平变换器输出电压谐波分析与抑制方法

Although many high-power voltage source converters are of three-phase three-wire type, there may also be other types of configuration with which tripplen harmonics in the ac voltage and/or current are of great concern. This paper analyzes the harmonic characteristic of the output voltage of modular multilevel converter (MMC) in cases where the third-order harmonic voltage and current are inevitabl...
