  Abstract

In this paper, we present a wireless power transfer (WPT) system with two receivers using an equivalent circuit model and derive a power transfer efficiency (PTE) at each receiver and a total system PTE. We demonstrate the analytical results by using circuit-level simulations with Advanced Design System, and show that there is an optimal placement of transmitter when the position of two receivers is fixed. In addition, in comparison with a WPT relay system, it is confirmed that the proposed system achieves higher PTE than the WPT relay system as the distance between transmitter and intermediate resonator is shorter. Otherwise, the WPT relay system achieves higher PTE than the proposed system.
