Temperature dependent analysis of thermoelectric module using Matlab/SIMULINK

This paper is an attempt of detail the comparative study of the analysis of thermoelectric module (TEM) for static and dynamic modeling with temperature dependent parametric variations. This study provides an insight on computation of various parameters of TEM used for modeling power generators. Initially a brief analysis is carried out for estimation of efficiency, power, voltage and current assuming a static model. Later dynamic model has been developed under MATLAB/Simulink environment with a consideration of its dependence with temperature and results of simulation are compared. Such comparative study not only validates the efficacy of the developed model with dynamic operating conditions but also pave the way for designing the balance of system more accurately. This paper presents a near accurate model of thermoelectric generator (TEG) with realistic conditions with a user-friendly approach. The inputs of the considered model are temperature dependent parameters, temperature of hot source and ambient temperature to which cold junction is exposed. The results are computed to evaluate the performance of TEM for generated voltage, power and efficiency.
