Energy Internet is a new type of power grid structure based on renewable energy power generation and distributed energy storage devices, and it is also a new trend of future power grid development. Energy router is the core part of the energy Internet, whose main task is to adjust the energy and information exchange. The H-bridge DC energy router, both as a variety of distributed energy generation device and load energy access internet interface, and can realize energy bidirectional flow and coordinated control. The structure has a stronger applicability to the in the energy Internet based on the DC micro grid, and has the advantages of simple structure, wide application range, low cost and etc, Firstly, this paper introduces the domestic and international development trends of energy router. secondly, the application domain and functional characteristics of the energy router are introduced. Once more, the working principle of H bridge DC energy routers are analyzed, and the simulation model of the H bridge DC energy routers is established by PSCAD. Finally, by building the corresponding experimental platform to verify the bidirectional energy flow in the H-bridge DC energy router.
