- An analysis model considered the manufacturing factors and the pellet size
has been developed in order to predict the performance characteristics of thermoelectric
modules as generators. Since the electrical internal resistance has a significant role in the
performance of thermoelectric modules, the variations of electrical internal resistance with
operating temperature are measured by experiment. The modified electrical internal resistance
calculated from experimental correlation is applied to the analysis model. To verify the
modified analysis model, the output voltage, output current and output power are compared
with experimental results for the operating temperature condition of Th=85℃ and ΔT=40℃.
The modified analysis shows a good agreement with the experimental results in terms of
the output voltage, current, and power.
