Abstract:
Thermoelectric Modules (TEM) are solid-state devices designed for energy conversion that can operate either as an electrical generator or as a cooling/heating device. This paper presents a measurement system for evaluating degradation caused by thermal cycles on TEM using a control-based testing platform that is capable of applying positive and negative temperature difference per cycle. In order to evaluate TEM degradation, the Harman method is used to assess TEM parameters. Experimental results show the efficiency of the proposed platform and in addition, a degradation mathematical model of the TEM is obtained.
