Abstract

Wireless Power Transmission (WPT) is a system that transfers electrical power from a source to a load without the need of solid conductors. Thus, there is a gap between the "transmitter" and "receiver". This technology can be useful in cases where interconnecting wires are inconvenient, dangerous or impossible. The most common type of WPT is through inductive coupling, which uses electromagnetic fields in coils to induce electrical current in the receiver. During studies and measurements in WPT systems, there is great difficulty to obtain specific equipment as well as to repeat the results of experiments. Motivated by this constant and noticed problem and also aiming to facilitate the introduction of this subject in graduation and technical courses, this project proposes the study of the WPT system and the development of techniques for assembling coils with different dimensions. It also intends to implement a methodology for testing the same. In a second stage, this project is planning to create and implement some workbench experiments as well as guidelines for the achievement of these experiments and apply them in the classroom to teach students in the areas of electronics and electromagnetism.
