Abstract

In an embodiment, a wireless power transmitter includes: a master transmitter resonant tank configured to wirelessly transmit power to a receiver resonant tank; a master transmitter driver configured to drive the master transmitter resonant tank; a slave transmitter resonant tank; a slave transmitter driver configured to drive the slave transmitter resonant tank; and a controller configured to adjust an impedance seen by the master transmitter resonant tank by controlling the slave transmitter driver, where controlling the slave transmitter driver includes adjusting a phase angle between a slave transmitter current flowing through the slave transmitter resonant tank and a master transmitter current flowing through the master transmitter resonant tank or adjusting a slave supply voltage of the slave transmitter driver.
