Análise experimental da transmissão de energia sem fios por modos ressonantes

Abstract

This work is performed a study and the development of a prototype for power transfer without the use of wires. Through an air core transformer with low coupling factor and, power transmission is performed with the satisfactory level from the resonant magnetic coupling. A literature review was made of the systems of structures used for wireless power transfer. The theory of coupled modes that provides the basis for the study of wireless power transfer by resonance is presented. Inductive element having the desired characteristics for the assembly of the prototype are designed. The factors that influence the efficiency of the transmission and reception are analyzed in order to improve system performance. Such systems can have numerous future applications, such as recharge portable devices, applications in medical diagnostic equipment or implants, as well as in electric vehicles.
