Voltage Balancing Strategy for V-Clamp Multilevel Converter Under High Modulation Index and High Power Factor Condition

Featured with the simple structure, V-clamp multilevel converter (VMC) shows good prospect in the high-voltage and high-power applications. But VMC is endangered by the deviation of dc-link capacitors voltage, especially under the high modulation index (MI) and high power factor (PF) condition. Thus...
