基于冗余电平调制的单端五电平NPC变换器快速电容电压平衡算法

Five-level neutral point clamped (5L-NPC) topologies have been proposed for the medium-voltage grid and drive applications since the 1990s. However, their practical implementation has been hindered due to the inherent capacitor voltage drift issue, especially in a single-end configuration. This work proposes a fast-processing, carrier-based voltage balancing algorithm to address this issue, which ...
