具有直流隔直电容的超宽输入电压范围混合型DAB变换器

In this letter, a hybrid-type dual active bridge topology with dc blocking capacitor for ultrawide input voltage is proposed. The proposed topology can expand the gain range by introducing voltage offset across the dc blocking capacitor, and has the ability to operate in single-stage or two-stage mode. The control strategy is also designed, which adopts the minimum resistive loss under the premise...
