Using PSPICE for electrical heat analysis

There are many tools available for thermal analysis and many available for electrical analysis. However, for those that require both (e.g. heater control systems, device temperature models, TEC modeling), the authors find that Orcad PSPICE, a registered trademark of ORCAD Corporation, is among the best. In fact, PSPICE is a fast and accurate tool for the thermal modeling of systems with a relatively small number of nodes. The authors aim to explain to the reader through step-by-step examples how to use PSPICE to perform this thermal modeling.
