Abstract: A dual active bridge converter includes a first full-bridge circuit and a high-frequency inductor. The first full-bridge circuit includes a first bridge arm including a first switching element and a second switching element connected in series. Methods of controlling a dual active bridge converter include detecting a voltage of the high-frequency inductor in response to the first switching element being turned off, setting a dead time according to a detection result of the detecting the voltage of the high-frequency inductor, and turning on the second switching element based on the dead time.
