DUAL ACTIVE BRIDGE CONTROL TO MINIMIZE DC LINK RESONANCE

Abstract: systems and methods for operating dual active bridge (dab) converters are provided herein. the systems and methods include sending a first control signal to toggle a first pair of switches of a bridge of the dab converter and sending a second control signal to toggle a second pair of switches of the bridge, where a temporal delay, based on a resonance time for the bridge, separates the toggling caused by the first control signal from the toggling caused by the second control signal.
