要約(英語): Wireless power transfer (WPT) via magnetic resonance coupling has been gathering attention because of its capability for highly efficient mid-range transmission and robustness to misalignment between the transmitter and receiver. Although the transmitting efficiency and charging power are determined by the coil parameters and load condition, their characteristics can be expressed based on the voltage ratio between the transmitter and receiver sides. In this paper, WPT systems are classified into four categories based on the design possibility and controllability of the system voltages on the transmitter and receiver sides. The design strategies of the system voltages are proposed, to give the priority operations for efficient power transmission and a stable power supply, considering power requirements and efficiency limitations. The experiments demonstrated the feasibility of the proposed method.
