Bidirectional DCDC Based Power/Signal Integrated Transmission in Energy Router

With the increasing popularity of the ubiquitous power Internet, how to construct a more convenient and efficient energy router has become a hot spot. In order to improve the compactness of the structure and reduce the cost, this paper proposes a power/signal composite transmission method based on dual active bridge topology. Bi-directional communication can be carried out directly on the power electronic converter, simplifying the structure of the energy router. In this study, power and communication are organically combined. The results show that this method can not only ensure the efficient and stable operation of the DAB converter but also accurately realize the bidirectional transmission of data, which provides a new possibility for the structural optimization of the energy router.
