In this paper, we present the dimensioning as well as the thermal and electrostatic modelling of a multilayer capacitor lowtemperature co-fi red ceramic (LTCC) to insert it in a Buck converter. We also present the diff erent stages of the realization of the LTCC capacitor. Our aims are volume and weight reduction, good frequency behaviour, low values of the series inductance and series resistance, and small ripples of the output voltage. The results obtained after the realization are satisfactory and encouraging, with a 92% reduction in volume and 99% in the surface area. To validate the correct operation of the capacitor, we used the PSIM simulation software to compare the voltage and current waveforms of the outputs of the Buck converter with a perfect capacitor and others with LTCC capacitor. COMSOL multiphysics simulation software allowed us to determine the operating temperature of the LTCC capacitor and to validate its electrostatic behaviour (distribution of electrical potential, of electrical fi eld and electrical current density). The multilayer capacitor is manufactured in the LAPLACE laboratory at Paul Sabatier University.

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 .
