This paper presents an analysis of the choice of integrated inductor for energy conversion in order to improve the DC-DC converter efficiency and their monolithic integration. A comparative study using two forms of turns, allowed to choose the best form of inductor which provides good values of inductance and quality factor for the same area occupied. In addition, a comparison of the inductors characteristics...
The aim of this paper is to combine the Bond Graph energy-flow modeling and the VHDL-AMS signal-flow modeling language for the simulation and the prototyping of modern switch-mode power converters. The proposed approach was used to model a specific test case, consisting of a Buck converter with a mixed-signal PWM regulator. The causal structure of bond graph paradigm provides the basis for the convergence...
The main objective of this paper is to develop a model of an inductor dedicated to the monolithic integration of DC / DC converters for mobile phone applications. Numerical simulation based on the finite element method shows that in contrast to 2D models, modeling of 3D integrated inductors can better estimate the electrical parameters of the desired inductor. The optimization of these values is based...
In this work we have developed and implemented on VHDL-AMS a model of the PiN diode, based upon the bond graph energy-flow modelling and the regional hypothesis. The PiN diode model is an association of several semiconductors region models. Each region is described by its important physical mechanism and the energy flow transfer between these regions is described by the bond graph paradigm. The primary...
