基于灵活混合虚拟SPWM方法的五电平变换器电压平衡控制

Flying-capacitor (FC) five-level topology with lower total blocking voltage is a potential topology in the medium-voltage application. Still, under high modulation indexes, conventional modulation methods cannot guarantee the stability of the FC voltage, resulting in increased volume and capacity of passive components and limiting its application. To achieve capacitor voltage balance at various mo...
