针对中点钳位型与飞跨电容型四电平变换器的广义低开关频率调制

Four-level neutral-point-clamped (NPC) and flying capacitor (FC) converters are suitable candidates for high-power medium-voltage applications due to their desired output performance and high power density. The major challenge on their successful applications lies in the dc-link capacitor and FC imbalance issue, especially for converters without redundant states that result in a significantly redu...
