integrated inductor with magnetic core takes into account all the technological parameters which are illustrated by analytic expressions. Moreover, the results of different simulations concern the effect of geometrical parameters of inductor on the inductance value and quality factor. Finely, we performed simulations on the operating of our buck converter including firstly an ideal inductor and then an integrated inductor with magnetic core. Simulation results have shown that the waveforms of the current and output voltage in both cases are similar.

based on the numerical analysis of the influence of the geometric parameters on the electrical characteristics of the solenoid inductor. The results simulation based on the MATLAB software. Finally, is discussing about the integrated solenoid inductor in a buck converter DC-DC, simulation results present by PSIM.
