一种用于五电平混合钳位变换器的低频电压纹波抑制与谐波增强的新型混合调制方法

The hybrid clamped converter cannot suppress low-frequency voltage fluctuations of the dc-link capacitors at low power factors. Rather, it exhibits a slow dynamic response and high output harmonics in such scenarios. To address this limitation, this study presents a novel hybrid modulation method that maintains the natural capacitor voltage balance while combining two basic modulation strategies: ...
