摘要： Polyphase wireless power transfer systems are provided. The transfer system may be used for charging hybrid and electric vehicles. The systems are capable of transferring over 50 KW over an air gap of 15 cm. The systems use a rotating magnetic field to transfer power. The system may comprise transmitter coil assembly. The coil assembly may be one or more layers. The system may employ either unipolar or bipolar coils. The transmitter also comprises compensating capacitance connected in series with at least one coil for each phase. A value of the compensating capacitance for each phase is determined such that the transmitter has at least two independently excitable resonant modes at a resonant frequency. The transmitter is compatible with a plurality of different receivers including three-phase, single phase with a circular coil and single phase with DD coils.

摘要： A wireless power supply power supply including first tuning circuitry coupled directly to a transmitter, the first tuning circuitry including an LCC configuration. The wireless power supply may include second tuning circuitry coupled directly to switching circuitry (e.g., an inverter) of the power supply, where the second tuning circuitry may be operable to direct power from the switching circuitry to the first tuning circuitry for supply to the transmitter, and where the second tuning circuitry includes a reactance operable to establish inductive operation of the switching circuitry at the switching frequency of the switching circuitry.
