“…Later, Yamaguchi and al proposed the first equivalent circuit composed of magnetic material placed above or below the inductance (Fig. 3c), but the model became very complicated [10]; afterward, this work was simplified to show the different layers superimposed one on the other (Fig. 3d) [11].…”

The work presented in this paper concerns the modeling of an integrated transformer in monolithic technology for high frequencies containing coils of planar type and magnetic circuit made of several layers of materials. Circular, square, and polygonal shapes of the planar coils are the important difference regarding transformer topologies. In this work, we have chosen the stacked octagonal form of coils. The transformer will be integrated into a converter of type flyback. We have opted for the Wheeler method and the S-parameters for determining the geometrical and the electrical parameters. The electrical π model presented summarizes perfectly the various parasitic effects generated by stacked layers of different materials constituting the transformer. The electromagnetic simulation, by using COMSOL Multiphysics 4.3 software, illustrates the current density and the distribution of magnetic field lines. We have also used software PSIM 6.0, to validate the equivalent electrical circuit of the transformer in flyback converter.

“…They are usually used in: power conversion integrated circuits [1,2], RF and microwaves passive components [3][4][5][6][7][8][9][10] and wireless communications devices [11,12]. For the fabrication of such inductors, two manufacturing technologies are generally used: Micro-Electro-Mechanical Systems (MEMS) and Monolithic Microwave Integrated Circuits (MMIC).…”

This paper presents two fabrication techniques of spiral integrated inductors based on magnetic materials. For the first one, the magnetic core is a thin film deposited by RF magnetron sputtering, for the second technique the magnetic core is a thick layer of YIG obtained by micromachining. The addition of the magnetic material is expected to improve the performances of the integrated structure with electromagnetic shield. Low and high frequency equipment are used to characterize the manufactured components. A good correlation is obtained between the results by simulation and measurements for the two manufacturing techniques. These results show that the inductance increases when the thickness of the magnetic layer increases, we can double the inductance value for a thickness sufficiently high.
