摘要： An inductively coupled power transfer receiver including a tunable circuit and a power supply circuit. The tunable circuit includes a power receiving coil in series with a first capacitance and a first variable impedance connected in parallel with the power receiving coil. The variable impedance includes at least one impedance element and one or more semiconductor devices for controlling the effective impedance of the first variable impedance. The first variable impedance may be a second capacitance in series with the first semiconductor device; an inductance in parallel with the first semiconductor device; a second capacitance in parallel with the first semiconductor device; or a capacitance and an inductor in parallel with the first semiconductor device. The power supply circuit includes a power control circuit which provides a control signal to the first variable impedance based on an output voltage produced by the power supply circuit.

摘要： A contactless power receiver is provided with a dynamically tuned pick up coil. The power transfer capacity of this power receiver is dynamically tuned using semiconductor devices that are operated in linear mode over part of their operation. The semiconductor devices are driven by a controller that is configured to implement a range of control strategies depending on system requirements. The semiconductor device may be used by itself or in conjunction with reactive elements to dynamically tune the pick up coil. In some implementations the contactless power receiver maybe configured to work with a consumer electronic or a wireless sensor device. The contactless power receiver can be integrated with the energy storage component of the device to provide a retrofit solution for existing products. The device can then be placed in vicinity of a planar magnetic field generated by a charging pad.

摘要： A contactless inductively coupled power transfer system is provided_including multiple pairs of power transmitter and power receiver coils and a power management module for controlling the supply of power to transmitter coils or the power supplied by the power receiver module to loads. The design is particularly suited for use in a wind turbine to supply power to the nacelle. The transmitter coils may be driven in phase at the same frequency or at different frequencies selected to avoid interaction between transmitter coils and the power transmitter module. The transmitter and receiver coils may be arranged in a traditional slip ring type configuration with adjacent coil pairs are physically spaced apart to avoid cross coupling with adjacent transmitter and receiver coil pairs shielded from each other. The power transmitter module may employ Zero Voltage Switching (ZVS).
