多电平DAB变换器电容电压平衡控制策略评估

Dual active bridge converter with multilevel neutral point clamped topology has shown potential to be a viable solution for medium-voltage dc systems. However, it will face a crucial challenge with regard to capacitor voltage balancing. In order to mitigate the negative effects caused by the voltage imbalance, e.g., overvoltage on certain devices, various control strategies for voltage balancing h...
