Simulation of thermoelectric generators and its results experimental verification

Thermoelectric generators (TEG) have been widely used as autonomous energy sources for a wide spectrum of applications that require output power from several mW to several W. The paper below presents simulation results compared to the experiments for the two mass production TEG types. TEGs have been simulated based on the finite element method (FEM) within ANSYS Workbench software platform, which allowed TEG workload mode and output power calculations within the operating temperature gap. The simulation results demonstrate appropriate compliance with the experimental measurements.
