Abstract

In this paper, we investigate a hybrid architecture of magnetic resonance multi-input multi-output (MIMO) and relay for wireless power transfer (WPT) network which both extend the power transfer distance and increases received power efficiency. We formulate the system model and derive the closed-form optimal beamforming solution. Then, we propose a hybrid transmitter (Tx) and relay coil placement algorithm, which is a linear searching scheme to find the optimal positions to provide the maximum uniform power distribution. The simulation results demonstrate that using the placement and beamforming algorithms can attain 2 to 5 times received power efficiency improvement, which is compared with equally assigned power on each Tx coil.
