Detailed study of the Dual Active Bridge
Dual Active Bridge dedicated to DC-DC conversion

Consisting of two inverters, the DAB is suitable for high-power applications. The high-frequency circuit consists of an inductor connected in series with the transformer. This combination also allows the leakage inductance to be used either on its own, or by reinforcing it with an external magnetic component. DAB's symmetrical structure inherently allows bidirectionality. Capacitive filters complete the converter to obtain, from the outside, voltage sources. In addition to filtering high-frequency currents, these filters clip the voltage across the MOSFET transistors. Figure
