Abstract
A method of wirelessly transmitting power includes: causing a power transmission circuit to transmit, to a master power reception circuit, a portion of power it is capable of transmitting; adjusting operation of a slave power reception unit until a first rectified voltage produced by the master power reception circuit and a second rectified voltage produced by the slave power reception unit are equal; causing the power transmission circuit to transmit additional power to the slave power reception unit, resulting in the first and second rectified voltages being unequal; and adjusting operation of the slave power reception unit until the first and second rectified voltages are again equal. A dummy load is connected to the slave power reception unit prior to causing the power transmission circuit to transmit the additional power, and is disconnected once the first and second rectified voltages are equal.
