| dc.description.abstract | Industrial Thermoelectric Generators (TEGs) with up to 10% energy conversion efficiency contribute to energy efficiency by using electrical energy to obtain heat from waste heat. The TEG internal resistance and the unequal load resistance considerably reduce the efficiency. Maximum Power Point Tracking (MPPT) algorithms are used to eliminate or minimize the imbalance between internal resistance and load resistance. In this study, the MPPT algorithm was modeled with MATLAB/Simulink by using the buck-boost converter to ensure the matching between internal resistance and load resistance based on Perturb and Observe (P&O). First, a TEG modeling was performed based on the Seebeck constant and temperature difference. In this modeling, after determining the TEGs to be connected in series and parallel, the variable load resistance was directly connected to the output of the TEG model. The output power of the TEG is calculated for the load resistance and the temperature difference values. In this case, it was determined that TEG without MPPT was highly affected by the load changes. The efficiency value is therefore continuously oscillating. Subsequently, this temperature difference change and the variable load were applied to the TEG system buck-boost converter with P&O MPPT. The TEG system with P&O MPPT algorithm was observed to track the Maximum Power Point (MPP) with an accuracy of 98.72% despite load and temperature changes. Thanks to the developed TEG system modeling of the P&O MPPT buck-boost converter, a simulation study is provided for the designers who will design the TEG system only to enter the Seebeck constant, series- parallel connected TEG numbers. | |
