Simulasi Daya Keluaran Generator Termolistrik (Gtl) Menggunakan Simulink pada Penjejak Maksimum dengan Algoritma Perturb and Observe (P&O)

Abstract

Research had carried out for the simulation to determine the power result of thermoelectric generator (TEG) by used the maximum tracer with the perturb and observed (P&O) algorithm. This simulation made was found and analyzed the value of the power generated by the TEG in converted heat into voltage. This simulation consisted of thermoelectric generator (TEG) module with parameters were adjust to the type TEP1-142T300, maximum power point tracking with P&O algorithm. a boost converter, and a resistance load. The thermoelectric generator functions to convert heat energy into voltage, this model depended on the difference between the hot and cold side temperatures, the number of modules, and the value of the Seebeck coefficient. The boost converter functions to increased the input voltage it received from the PWM block in the form of a duty cycle based on the perturb and observed (P&O) algorithm. It could be analyzed that when the TEG had a temperature difference on the cold side and the hot side, it will generated a voltage. Therefore, a temperature variation was carried out at the TEG by keeping the load value at 20 Ω. This study also uses a load variable, to determined the effect of resistance on the power generated by the TEG, In this study, the temperature value is kept constant each at 100℃ and 31.75℃. At the variable of load, the power would change for a changed of load and would maximum value when the load resistance was equal to the internal resistance
