In this paper, we proposed an equal power allocation method to two receivers with high efficiency in two-dimensional wireless power transfer (2D-WPT). We conducted the computer simulation of the 2D-WPT to two receivers by using the circuit simulator that applied the equivalent circuit of magnetic resonance coupler arranged on 3×3 layout. As the result, the 2D-WPT showed unequal power allocation to two receivers because of the interference between multiple paths with different hop counts. Therefore we developed the single-path control method that improves efficiency by ON-OFF control of intermediates so as to form only one path to each receiver. As the result of circuit simulation and experiments, the efficiency using single-path control achieved higher and equal power allocation to two receivers.
