Abstract:Design of integrated power systems requires prototype-less approaches. Accurate simulations are necessary for analysis and verification purposes. Simulation relies on component models and associated parameters. The paper focuses on a step-by-step extraction procedure for the design parameters of a one-dimensional finite-element-method (FEM) model of the PiN diode. The design parameters are also available for diverse physics-based analytical models. The PiN diode remains a complex device to model particularly d… Show more
“…While power MOSFETs (metal-oxide semiconductor fieldeffect transistors) are typically used in high power converters [16,17], they are not suitable for integrated converters due to the medium voltage and power ratings [18]. Therefore, CMOS (complimentary metal-oxide semiconductor) transistors are used in integrated DC-DC converters.…”
This paper presents a design procedure of an integrated inductor with a magnetic core for power converters. This procedure considerably reduces design time and effort. The proposed design procedure is verified by the development of an inductor model dedicated to the monolithic integration of DC-DC converters for portable applications. The numerical simulation based on the FEM (finite elements method) shows that 3D modeling of the integrated inductor allows better estimation of the electrical parameters of the desired inductor. The optimization of the electrical parameter values is based on the numerical analysis of the influence of the geometric parameters on the electrical characteristics of the inductor. Using the VHDL-AMS language, implementation of the integrated inductor in a micro Buck converter demonstrate that simulation results present a very promising approach for the monolithic integration of DC-DC converters.

Section: Equivalent Thermal Model Of a Power Diode Packagementioning
-This paper presents a PFCVF (Power Factor Correction) rectifier that uses a variable frequency source for alternators in electric and hybrid vehicles application. This technique allows to preserve a good THD (Total Harmonic Distortion) of the input source at any frequency and to decrease losses in semiconductors switches, thereby permitting more stability and decreasing the apparent power requirements. A comparative study between the standard and the new technique is made. A thermal network is used to calculate the junction temperatures in order to estimate the equivalent losses in the rectifier with respect of junction temperature modifications and power equilibrium. The relations of the proposed model are defined and simulation results as well as experimental results are discussed.
“…p + /i and i/n + junctions, the carrier transit time must be defined. So, by varying the depletion region width in the power PIN diode model with respect to the two (8) and (9), the carrier transit time T M will be varied and the following equation is crucial for establishing this relation:…”

“…In fact, as stated in [8], probes interact with the device under test, create delays due to propagation in the cable and worst of all degrade the signal due to distortion in the probes and the cables. The overall accuracy of the extraction procedure requires the probe effects to be taken into account in simulation.…”
Section: Comparison With Experimental Datamentioning
This study focused on the determination and analysis of an accurate analytical model for PIN diode under different bias conditions. This approach employs analytically derived expressions including the variation of the depletion regions in the device to make the used model available over a wide range of testing conditions without remake the parameters extraction procedure. The validity of the proposed extraction procedure has been verified by the very good agreement between simulated and measured current and voltage waveforms reverse recovery at different range of the operation conditions. The model is developed and simulated with the VHDL-AMS language under Ansoft Simplorer® Environment.
