Integrated Square On-Chip Inductor for Photovoltaic Converter Applications

The research of this paper concerns the study of an integrated square on-chip inductor in a DC-DC Buck converter connected to a photovoltaic module. The topology of the inductor is chosen for its ability to provide improved performance and high inductance value. The paper presents the integrated inductor geometrical and electrical dimensioning. The equivalent electrical circuit of on-chip inductor with different added layers is described. The finite elements method is used to illustrate the current density and temperature distribution in the on-chip spiral inductor. The simulation of the DC-DC Buck converter with PV panel is validated using the integrated inductor to show its performances. The study combines theoretical analysis, modeling and simulation techniques to evaluate the performance and effectiveness of the square on-chip inductor topology. The results obtained provide valuable insights into the design and operation of the integrated inductor based PV system.
