Abstract

A wireless power transmission method of control is disclosed where equalization of the reactive voltages of a series resonant circuit, which is part of a transmitter antenna tuning and coupling unit, is obtained by adjusting the switching frequency and thereby used to determine a switching frequency of the driving high frequency inverter. By measuring and largely equalizing the voltage parameters of the series resonant circuit to establish an inverter switching frequency, improved efficiency of the wireless power transmission method.
