In this digest, a dual-input dual-active-bridge (DAB) dc-dc converter is presented at first. Different from the existing three-port DAB dc-dc converter, the presented converter topology eliminates a redundant power transferring inductor. Then, the power coupling among these three ports can be reduced significantly, which is beneficial to realize the flexible power management of this converter. Moreover, a decoupling power sharing control scheme for a dual-input dual-active-bridge (DAB) dc-dc converter topology is proposed, hence decoupling power sharing among each port and realization of the model-based control method for better dynamic performance can be achieved. The effectiveness of the proposed control scheme is verified using the simulation and experimental results obtained from the hardware prototype.
