Numerical modeling of thermoelectric generators with varing material properties in a circuit simulator / Min Chen in IEEE transactions on energy conversion, Vol. 24 N°1 (Mars 2009)  

Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 24 N°1 (Mars 2009) . - pp. 112 - 124 Titre : Numerical modeling of thermoelectric generators with varing material properties in a circuit simulator Type de document : texte imprimé Auteurs : Min Chen, Auteur ; Rosendahl, L. A., Auteur ; Condra, T. J., Auteur Année de publication : 2009 Article en page(s) : pp. 112 - 124 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Circuit simulation  numerical analysis  power system thermoelectric conversion Résumé : When a thermoelectric generator (TEG) and its external load circuitry are considered together as a system, the codesign and co-optimization of the electronics and the device are crucial in maximizing the system efficiency. In this paper, an accurate TEG model is proposed and implemented in a SPICE-compatible environment. This model of thermoelectric battery accounts for all temperature-dependent characteristics of the thermoelectric materials to include the nonlinear voltage, current, and electrothermal coupled effects. It is validated with simulation data from the recognized program ANSYS and experimental data from a real thermoelectric device, respectively. Within a common circuit simulator, the model can be easily connected to various electrical models of applied loads to predict and optimize the system performance.
