Abstract
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.
