Combined Electrical and Thermal Circuit Simulation Using APLAC. Part A.Implementation and Basic Component Models

摘要

We present the implementation of combined electrical and thermal analysis in thegeneral purpose circuit design tool APLAC. The thermal properties of the components are modeled in a well-known way using an electrical equivalent circuit. Using the suggested methods, the self-heating phenomenon is included in any power-dissipating component model, if desired. The electrothermal component models each include a thermal network whose parameters are defined like any other model parameters. These component models are available in all elementary analysis modes; no special electrothermal analysis method is required. This report presents several models for heat transfer using electricial equivalent circuit. Electrothermal component models for resistor, capacitor, inductor, and controlled sources are discussed in detail, and simulation examples are given.(Copyright (c) 1995 by Helsinki University of Technology.)
