Abstract: A wireless power transmitter is provided herein. The wireless power transmitter includes a coil, transistors, and a controller. The coil provides a magnetic field for a wireless power transfer in accordance with an alternating current power supply providing an alternating current input at a first frequency. The transistors couple to a phase and a zero of the alternating current power supply. The controller switches the plurality of transistors at a second frequency to drive a current across the coil that induces the magnetic field. The current includes an envelope that corresponds to the first frequency of the alternating current input.

Abstract: A method may comprise determining a coupling factor between a coil of a transmitter and a coil of a relay based on a joint resonance frequency between the coil of the transmitter and the coil of the relay. The determining may occur when the coil of the relay and the coil of the transmitter are separated by a medium. The transmitter may inductively transmit power for wirelessly charging a device located near the relay. An operating frequency range, having a minimal operating frequency and a maximal operating frequency, may be determined based on the coupling factor. Power may be inductively transmitted in accordance with the minimal operating frequency and the maximal operating frequency.
