Switched Amplifier Resonant Inductive Wireless Charging Setup for Electric Vehicles

This paper presents wireless charging setup for electric vehicles based on resonant inductive power transfer topology. Since the input power is fed from DC microgrid, this charging topology encourages the use of renewable energy sources like solar and wind. The wireless charging setup consists of different components such as DC microgrid, switching and power amplifier, transmitter-receiver setup and rectifier. A wireless charging setup based on resonant inductive power transfer is implemented and the performance of the prototype is analyzed using relevant waveforms.
