Abstract

The optimal excitation of multi-transmitter wireless power transfer systems is dependent on the position of the receiver (Rx), To maximize the output power and efficiency, the transmitter (Tx) coils closer to the Rx should have higher currents compared to the ones farther away. This paper presents a simple approach to determine the optimal excitation of individual Tx without using any measurement at the Rx side. The Tx coils are arranged to be uncoupled from adjacent Tx coils. In this configuration, the optimal current distribution in each Tx coil is a function of the mutual inductances of each Tx-Rx coil pair, which can be evaluated by analyzing the voltage measurements at Tx coils. The proposed approach is experimentally verified using a laboratory prototype.
