Abstract

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 on the numerical analysis of the geometrical parameters influence on the inductor electrical characteristics. The VHDL-AMS simulation results of the optimal inductor implemented in a micro-converter prove that it has a very promising approach for the DC/DC monolithic integration converters.
DC/DC变换器集成硅功率电感的三维数值分析
本文的主要目的是开发一种专用于移动电话应用的DC/DC转换器单片集成的电感器模型。基于有限元法的数值模拟表明,与二维模型相比,三维集成电感器建模能更好地估计所需电感器的电气参数。这些数值的优化是基于几何参数对电感电特性影响的数值分析。在微变换器中实现的最优电感的VHDL-AMS仿真结果证明了它在DC/DC单片集成变换器中具有很好的应用前景。
