The influence of ferrite on the spiral inductors inductance used for the design of wireless power systems

Increasing the number of electric/electronic devices powered with electric power, has led to a series of different chargers and a mixture of wires spread through the house or office. For a long period of time, the concept of charging without any direct connection through wires was avoided, but the last few years show an increased interest to make the loading with electrical power more flexible and easier to use. In this context, the work has as its main objective the practical realization and analysis of power systems for electrical and electronic devices. Therefore, it is necessary to create and analyze multiple types of spiral inductors to achieve a feeding device with higher performance.
