Network pattern for mid-distance wireless power transfer in local area

Wireless power transfer (WPT) based on magnetic resonant coupling is a novel technology by which non-radiative and mid-range power transfer can be realized via the near field. WPT inevitably leads to a small-scale regional network with a certain amount of transmitters, receivers and repeaters. There is a great lack of related analysis approaches because of its high-frequency and near-field features, which are quite different from those of microwave network and industrial frequency alternating current network. These make it difficult to establish networks with high degree of autonomy. Inversely, presented centralized supervision mode with a specialized power monitoring and management unit is expected to operate well, gathering devices parameters and service states, analysing network operating performance, such as power spatial and temporal distribution, frequency bifurcation phenomenon, and the impacts of moving and switching of the loads, etc., and then making schedules and decisions. It hence does guarantee the availability, reliability and stability of WPT local area network.
