摘要： A communication system that uses keyed modulation to encode fixed frequency communications on a variable frequency power transmission signal in which a single communication bit is represented by a plurality of modulations. To provide a fixed communication rate, the number of modulations associated with each bit is dynamic varying as a function of the ratio of the communication frequency to the carrier signal frequency. In one embodiment, the present invention provides dynamic phase-shift-keyed modulation in which communications are generated by toggling a load at a rate that is a fraction of the power transfer frequency. In another embodiment, the present invention provides communication by toggling a load in the communication transmitter at a rate that is phase locked and at a harmonic of the power transfer frequency. In yet another embodiment, the present invention provides frequency-shift-keyed modulation, including, for example, modulation at one of two different frequencies.

摘要： A power supply to provide electrical power to one or more loads. The power supply may include a resonant air core transformer to provide an adjustable and adaptable source of power to electronic devices. The power supply may include isolated primary-side circuitry and secondary-side circuitry. The primary-side circuitry may include control circuitry that, among other things, provides drive waveforms for the primary-side switching circuitry. In embodiments configured to produce AC output, the secondary-side circuitry may also include switching circuitry. The primary-side control circuitry may provide drive waveforms for the secondary-side switching circuitry. The secondary-side circuitry may include measurement circuitry that measures the current and/or voltage of the output and provides those measurements to the control circuitry through isolation circuitry. The control circuitry may adjust the drive waveforms for the primary-side and/or secondary-side switching circuitry as a function of the measured values.
