Abstract :
Wireless power transfer system with coil arrays which can supply to several apparatus at the same time is expected. In this case, only one or two primary coils under the secondary coil are excited. The electromotive force of the secondary coil is changed by the interval of primary coils and the number of the excited coils. In this paper, the effective equivalent circuit which could reproduce this behavior is presented.
