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.
