摘要： The disclosure features wireless power transmitters that include a power source, a first coil connected to the power source, a second coil connected in series to the first coil, and a third coil positioned in proximity to the second coil, where during operation of the wireless power transmitters, the power source applies a driving voltage to the first and second coils, the first coil generates a first magnetic field that transfers power to a receiver resonator, the second coil generates a second magnetic field that induces a voltage across the third coil, and the induced voltage across the third coil is applied to a component of the wireless power transmitters.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for dynamically tuning circuit elements. One aspect includes a variable capacitance device. The device includes a first capacitor, a first switch, a second capacitor, a second switch, and control circuitry. The control circuitry is configured to adjust respective capacitances of the first and second capacitors by causing a first control signal to be applied to the first-switch control terminal for a duration of time in response to detecting a zero voltage condition across the first switch, and by causing a second control signal to be applied to the second-switch control terminal for the duration of time in response to detecting a zero voltage condition across the second switch.

摘要： Improved configurations for wireless energy transfer can include system elements of a wireless energy transfer system that may pair in-band and out-of-band communication channels by exchanging related information. Energy transfer signals may be modulated according to defined waveforms. Information about the signal may be transmitted using an out-of-band communication channel. A system element that receives both the signal and information may verify that they correspond to the same system element.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for dynamically tuning circuit elements. One aspect includes a zero voltage switching device including a switch, a first comparator, a second comparator and a controller. The switch includes a first terminal, a second terminal, and a control terminal. The first comparator includes a first input terminal electrically connected to the second terminal of the switch and a second input terminal electrically connected to the first terminal of the switch. The second comparator includes a first input terminal electrically connected to a reference voltage and a second input terminal electrically connected to the control terminal of the switch. The controller is configured to: detect a zero voltage condition across the switch, and, in response, cause a control signal to be applied to the control terminal of the switch.

摘要： The disclosure features apparatus, methods, and systems for wireless power transfer that include a power source featuring at least one resonator, a power receiver featuring at least one resonator, a first detector featuring one or more loops of conductive material and configured to generate an electrical signal based on a magnetic field between the power source and the power receiver, a second detector featuring conductive material, and control electronics coupled to the first and second detectors, where during operation, the control electronics are configured to measure the electrical signal of the first detector and compare the measured electrical signal of the first detector to baseline electrical information for the first detector to determine information about whether debris is positioned between the power source and the power receiver.
