Methods of Temperature Measurement in Magnetic Components

Abstract

In this paper, we reveal the different temperatures recorded in selected magnetic components and, we show the methods of determination and measurement used. As magnetic components have characteristics that strongly depend on the level of local temperature, it is essential to take into consideration the temperature and its influence on the magnetic and electrical characteristics of the component. From the modeling objectives, we describe the constitution, the originality and the main functions of the device used to determine the temperature of the material, its winding, and connection. Finally the result of deepened tests will be presented, allowing to determining parameters of our model. Our work focuses on the development of thermal models capable of determining the working temperature of the chosen magnetic component at given points. It aims to help develop a methodology for designing thermal models of magnetic components; an approach that will be validated through a practical demonstration.
