The soft magnetic materials for power applications

In this paper, we examine the role of soft magnetic materials especially the MnZn ferrite in high-frequency power applications and we discuss some potential applications such as the transformer design which based on MnZn ferrite core and electrical machine design using these magnetic material which take into account their electrical and magnetic properties at the microscopic scale such as magnetization phenomenon, as well as its influence on macroscopic properties, the resistivity and the magnetic losses. Relatively due to the magnetic structures of the considered materials, we can introduce the notion of power conversion, leading to an understanding of the operation of various electromagnetic devices.
