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.

Abstract: An inductive power transmitter having a plurality of transmitting coils for generating an alternating magnetic field arranged in a row with each transmitting coil partially overlapping with adjacent transmitting coils in the row. A transmitting circuit connected to each transmitting coil may drive the transmitting coils so that each transmitting coil's alternating magnetic field is phase shifted with respect to the alternating magnetic field of adjacent transmitting coils in the row or so that the alternating magnetic field generated by the transmitting coils travels along a charging surface.
