Title: Dual-frequency mode transmitter for wireless power transfer

Patent ·
OSTI ID:1650838

A transmitter for wireless power transfer is provided. The transmitter includes an input port, a first transmission port, a second transmission port, an inverter, and a controller. An input of the inverter is coupled to the input port, and an output of the inverter is coupled in parallel to the first and second transmission ports. The controller is programmed to control the inverter to modulate an output voltage at the output of the inverter such that power from the input port is transmitted at a first frequency through the first transmission port and at a second frequency through the second transmission port.
