适用于超宽输入电压范围的混合型双有源桥DC-DC变换器

This article proposes a hybrid-type dual active bridge (H-DAB) topology and extended gain (EG) control method applied to the ultrawide input-voltage range. The H-DAB is obtained by adding an auxiliary half-bridge to the conventional current-fed dual active bridge (CF-DAB) topology. The auxiliary half-bridge can assist the CF-DAB to achieve zero voltage switching (ZVS) on the one hand and further e...
