    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.
