Abstract

This research explores the potential of wireless energy transmission systems (WETS). Basically, WETS transfers electric energy from a source circuit to a load circuit without the need of physical conductors, i.e., there is a space between the "transmitter" and the "receiver" circuits. The use of this type of technology can be very useful in the cases where physical wires are inconvenient, dangerous or impossible. The most common technique of WETS is done through inductive coupling. This coupling uses magnetic fields from the transmitter coil to generate electric current in the receiver coil. However, electric circuit models which represent these systems with reliability are still not well known. The knowledge of these models would facilitate the study and assembly of more efficient and safe WETS. Thus, the use of software to analyze several different electric circuits becomes necessary. Hence, the first step of this project will be the study of concepts of transformers, optimization technics and MatLab. The circuit simulations that will be performed and the identification of its parameters will supply a reliable circuit. The evaluation of the results will be done by comparing the data obtained by the electric circuit model with the supplied data of the WETS coils. At the end of this research, the final results are intended for the presentation in conferences.
