Abstract

Wireless power transfer (WPT) system based on magnetic resonance is presented here. The aim is to transfer energy wirelessly from transmitter coil to receiver coil based on magnetic resonance. A novel system with a two-coil transmitter connected to a single power source is proposed here in a triplet configuration with a single receiving coil. The two-coil transmitter is introduced as an extension to the converge area. The equivalent lumped element circuit model is presented and mathematical equations for scattering parameters have been derived. The proposed configuration is simulated using both circuit (ADS) and electromagnetic (EMPRO) simulators. The effect of the coupling between coils is investigated using simulation. The proposed configuration is practically implemented using solenoid coils and tested to verify the simulation results. The effect of receiver displacement on efficiency is also investigated.
