用于双极性直流配电的具有自动电压平衡功能的三有源桥变换器

The bipolar dc grid outperforms the conventional unipolar dc distribution in terms of quality, flexibility, efficiency, reliability, transmission capacity, and safety. Despite many advantages, it has a voltage imbalance problem. Unbalanced and asymmetrical load conditions are the major contributors to this imbalance. This article proposes the triple-active-bridge converter with an automatic voltag...
