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.2
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.

For the sake of reducing the size of the power converters for photovoltaic applications, the microelectronics industry knows a permanent race in order to reach out to integrated electronic components with high efficacy and low losses for different applications. This paper presents a detailed study for designing an integrated structure with a dual-layer inductor model associated with two layers of MPP Molypermaloy magnetic cores. This inductor is intended to a DC–DC boost converter for photovoltaic application purposes. With an input of 17 V, 220 V output and supports a maximum current of 7 A on an operating frequency of 500 kHz with an output ripple less than 0.8%. The research covered the impact of coil's conductor thickness on the inductance. The gap effect study reached to determine the optimum gap between coils permit for the better profiteering of the mutual inductance with low losses. The transmission lines method was used to determine the equivalent electrical circuit for the designed dual-layer inductor to investigate the losses due to the parasite-flowing currents, also, to validate the performance and the well operating of the inductor in the application. The study investigated the magnetic behaviour and current density in conductors by numerical simulation governed by Maxwell's equations and solved by fi nite element method. An algorithm has been associated with the converter to compensate all losses and ensure the stability of the output voltage. The designed inductor has an inductance of 14.2 μH and covering a volume of 10 mm× 10 mm × 2.07 mm .
