| Abstract(in English) | Characteristics of a wireless power transfer system depend on characteristics of coils. Resonant coil is used for wireless power transfer in the case of magnetic resonant coupling type. Resonant capacitor used for resonating with coil has problem of withstand voltage. High voltage is applied to resonant capacitor because of high Q coil, and can cause breakdown accident. Capacitor-less wireless power transfer can prevent this accident. In case of wireless power transfer for electric vehicles, 85 kHz is used as resonant frequency. In this paper, design method of self-resonant open end coil which resonate at 85 kHz is proposed. Characteristics of the proposed coil is verified by experiment. |
