  • Capacitive power transfer system with integrated wide bandwidth communication
    Patent number: 11996698
    Abstract: A capacitive power transfer system can include a power transmitter having one or more primary side filter components, a communications modulator, and transmitter capacitive couplers; and a power receiver having receiver capacitive couplers capacitively coupled to the transmitter capacitive couplers, one or more secondary side filter components, and a communication demodulator. The one or more primary side filter components and the one or more secondary side filter components can be selected to provide power amplifier operation at a power delivery frequency and act as a stable gain high pass filter above a communications cutoff frequency that is higher than the power delivery frequency.
    Type: Grant
