Wireless Power Transfer Using Class-De Converter Via Strongly Coupled Two Planar Coils

Abstract

WIRELESS POWER TRANSFER USING CLASS-DE CONVERTER VIA STRONGLY COUPLED TWO PLANAR COILS by Ayetullah Bahadir Biten The University of Wisconsin – Milwaukee, August 2016 Under the supervision of Professor Adel Nasiri Wireless power systems are getting popular with the improvement in the technology not just because it is a fancy and cool conception but also because it is more convenient and safer in some applications. For example, this project aims to help high power data center design to be changed to wirelessly powered center to provide a safe and hands-on work environment even under different load conditions. Thinking of the basic conception of magnetic induction theory, electric power ranging from microwatts to thousand watts can be wirelessly transferred from one coil to another without having a core material. The purpose of this project is to apply high efficiency class-de converter methodology to obtain alternating current so that this alternating current is transmitted from primary coil to secondary while being stepped up as required within the project specifications. At the load side is a full bridge diode rectifier that is converting the captured alternating current back to direct current. In the scope of this project, mathematical calculations for the circuit elements’ values under the class-de power amplifier topology, simulation results, and feedback control method will be discussed.
