The aim of this paper is to present a work strategy uniting simulation and experimental results in order to optimize the design of two types of circular spiral inductors: standard and variable width spiral for the purpose of realize them. These inductors will be integrated in a boost micro converter. At first, we present the geometrical and electrical modelling of these inductors. We propose a comparison between the electrical and the electromagnetic behaviour of a standard and a tapered coil at 3 MHz. An application of our components in a boost micro converter is presented. The results presented in this article are based on the following characteristics of micro converter: output voltage 3 V, maximum current 5 A, output power 3.75 W, frequency of operation 3 MHz. The schematic simulation allows to explicit the behaviour of the inductor and the micro converter by analysing the wave’s form of currents and voltage. The prototyping process and the characterization of inductors took place at LAPLACE laboratory, Team MDCE, Toulouse, France.

Conception and Manufacturing of a Planar Inductance on NiFe Substrate
Fatima Zohra Medjaoui,Azzedine Hamid,Yacine Guettaf,Pierre Spiteri,Vincent Bley 한국전기전자재료학회 2019 Transactions on Electrical and Electronic Material Vol.20 No.3
The present paper presents the study, realization and characterization of a micro-coil sandwiched using a relatively thick layer of magnetic material. The integration of this micro-coil with as a starting point a set of specifi cations, requires the following steps: Identifi cation and validation of geometric parameters for the calculation of electrical parameters. Losses dissipated as heat in these electronic systems are becoming a major concern for designers. This prompted to take into account the thermal design. The results obtained have allowed to realize a micro-coil micro square planar coil sandwiched shaped between two magnetic materials. Several carried measures focused on the inductance and resistance which are related to the frequency f , the module and phase of the impedance, and the gap g . The operation of these data is used to trace the evolution of theinductance value L s , the quality factor Q and the resistor R s as a function of frequency.

Magnetothermal behavior of a planar coil

The world of microelectronics is punctuated by the permanent race for integration, in order to be able to reduce the sizes, costs and power consumption of products. The largest discrete components which are seek today are passive elements, present in an increasingly important proportion. In circuits (resistors, inductors and capacitors). The scientific research aimed at highlighting the magnetothermal behavior of this type of component shows a certain deficit. In this regard, this paper presents an investigation by way of numerical simulation of the magnetothermic behavior, allowing the enhancement of the design of a square planar coil sandwiched between two magnetic materials. It is intended to be inserted in a micro-converter of Buck type. The phenomenon studied is governed by Maxwell’s equations coupled with the heat equation, which are solved by the finite element method. The heat transfer processes by conduction and by convection are taken into account in steady state. Gap effects are considered as a control parameter on the magnetic, electrical and thermal behaviours, in order to determine it’s the optimal value allowing to have the best inductor operation while having an optimum cooling ratio. The materials composing this structure do not react in the same way to temperature variations, which will generate stresses in the materials that compose it and render it non-functional. The numerical simulation results show the distribution of the magnetic field, the role of the different materials constituting the substrate and the temperature distribution. On the other hand, they made it possible to optimize the gap value, which is considered as an important parameter during the dimensioning of the microcoil to determine the optimal geometric parameters.
