  • Coupled-coil power control for inductive power transfer systems
    Patent number: 10020687
    Abstract: An inductive power transfer device including: a resonant circuit, having a power transfer coil and a power transfer capacitor; a coupling coil, magnetically-coupled to the power transfer coil; a variable impedance; and a controller configured to determine the impedance value of the variable impedance based on predetermined criteria including: substantially regulating power provided to a load; tuning the resonant circuit resonant frequency substantially to a predetermined frequency; adjusting a frequency of a magnetic field associated with the power transfer coil; and/or adjusting an impedance reflected by the power transfer coil to a corresponding coupled power transfer coil.
    Type: Grant
