  • Variable-distance wireless-power-transfer system with fixed tuning and power limiting
    Patent number: 10483810
    Abstract: A wireless-power-transfer system includes a transmitter circuit and a receiver circuit. The transmitter circuit includes a primary series-resonant capacitor connected to an oscillator-controlled drive stage that provides fixed-frequency output and a transmitting coil connected to the primary series-resonant capacitor. The transmitting resonant frequency is below the fixed frequency of the oscillator-controlled drive stage. The receiver circuit includes a receiving coil, a secondary series-resonant capacitor connected in series with the receiving coil, and a secondary parallel-resonant capacitor connected in parallel with the receiving coil. The receiving resonant frequency increases as a nonlinear capacitance of the at least one rectifier decreases when the rectifier-circuit DC output increases.
