Abstract: The embodiments relate to a real-time approximation method and apparatus of a mutual inductance between transmitters and receivers for determining an optimal operating condition in a multiple-receiver wireless power transfer system, and it may be configured to approximate a mutual inductance in the multiple-receiver wireless power transfer system according to a configuration status of the receivers, and determine an operating condition of the multiple-receiver wireless power transfer system based on the mutual inductance. According to the various example embodiments, the inductance may comprise a mutual inductance between the transmitter and the receivers, and a mutual inductance between the receivers.
