一种用于多电平DAB变换器的无模型电容电压平衡方法

Capacitor voltage balancing is of importance in the neutral-point-clamped based dual-active-bridge converters. Most of traditional voltage balancing methods adopt the transformer current models in the balancing process, as the direction of the neutral-point current is affected by the transformer current polarity. However, this approach requires heavy and repetitive offline precalculation for the t...
