“…10. By controlling the intra-bridge and inter-bridge phase shift of DAB, power flow can be controlled flexibly [30], [31]. Similar to Buck/Boost IIC, there are also four operation modes for the DAB IIC, including: 1) Sleep mode: All the MOSFETs are off and the power link voltage remains zero.…”

This paper proposes a novel embedded communication strategy for in-home energy routers (IHER). It is based on power/signal dual modulation principle, and applied in the small scaled community energy local area network (E-LAN). The proposed communication strategy multiplexes power converters as data transmitters, and thus highly cooperation and synchronization between power flow and information flow are achieved. Besides, system reliability is enhanced since communication module has practically the same reliability as the power module. A typical IHER's structure and operation principles are presented, based on which detailed design of embedded communication is proposed. For distributed power management of community E-LAN, both intra-IHER communication and inter-IHERs communication are involved, and their channels are modelled mathematically. IHER interconnection interface converters play a significant role in power exchange between IHERs, and their operation modes are analyzed in detail. Finally, an experimental prototype is built to validate the feasibility of the proposed method. Index Terms -Power/signal dual modulation (PSDM), Embedded communication, In-home energy router (IHER), Energy Local Area Network (E-LAN) I.INTRODUCTIONThe need to diversify away from fossil fuel generation due to concerns over energy security, fuel price volatility, and the climate challenge is driving the deployment of nonconventional renewable energy (wind, small hydro, solar, tidal, geothermal and in some cases waste) [1]. Because of their distributed, intermittent and fluctuated characteristics, energy management is considered as a key paradigm for the realization of complex energy systems [2]-[4], and distributed power management and flexible bidirectional power flow control are required. Energy Internet (EI) concept has been proposed [5]-[7] as a feasible solution, which deeply integrates energy technology and information technology, presenting a green vision of evolution [8]-[10].Currently, EI has received extensive attention and several structures have been proposed [11]. Generally, there are three mainstream structures, which are bus structure, tree structure and mesh structure [12]. Bus structure has great advantages of extension, but the common bus encounters congestion challenges in condition of large scaled power and information interaction. Tree structure can efficiently isolate fault, however, it faces the bottleneck of efficient power control and management in promotion. Mesh structure does not need central controller and gives more autonomy to energy entities, achieving better robustness and fault tolerance [13]. It requires high cooperation and synchronization between power module and communication module to guarantee distributed, reliable and flexible power management, and it is usually applied in small scale energy local area network (E-LAN), such as a residential community energy network.In a community E-LAN, the IHER plays a significant role as the key element, interconnection equipment and power management units ...

As a power electronic converter with bidirectional energy transmission, the Dual Active Bridge (DAB) has a broad application prospect in the electrical power distribution system of hybrid‐electric flight. For the DAB application in the electrical power distribution system, high efficiency and high reliability are envisaged due to the mission‐critical nature of the application. A new pulse width modulation optimization control strategy is proposed, which is based on the feedback temperature fluctuations of the GaN (Gallium Nitride) power transistors, to improve the lifetime of the whole circuit. The complete topology and simulations of the DAB converter are carried out in PLECS. Detailed simulation results manifest the precise lifetime of the GaN power transistors and verify the accuracy of the new optimization control strategy. Meanwhile, Insulated Gate Bipolar Translator is set as a control group to compare the lifetime of conventional silicon‐based power devices with the GaN power transistor. Hardware In Loop platform test is built to further validate the proposed method.

“…Single-phase shift (SPS) is a very common dual active bridge control scheme. The SPS phase shift preserves the direction of voltage and power flow on both sides of the high-frequency transformer [5]. Because of the high circulating current, when the voltage amplitude of both the SST side is unbalanced, there is an increase in the resulting (1) A dual active bridge DC-DC converter closed-loop control system has been used in which the secondary H-Bridge output voltage (VO) is compared with the reference voltage value (Vref).…”
