A DC/DC converter applies a dual active bridge (DAB) topology to convert an input DC voltage into an output DC voltage. The DC/DC converter includes a transformer, a primary stage, and a secondary stage. The primary stage includes an inductor, a first H-bridge arm having first and second power switches connected at a first node therebetween, and a second H-bridge arm having first and second capacitors connected at a second node therebetween. The inductor is connected between the first node and a terminal of an input port of the primary stage. The primary stage receives the input DC voltage at the input port of the primary stage and converts the input DC voltage into a first AC voltage. The transformer transforms the first AC voltage into a second AC voltage. The secondary stage converts the second AC voltage into the output DC voltage.
