Modeling and simulation of thermo electrical generator with MPPT

Abstract

Nowadays, thermo electrical (TE) modules are increasingly popular because their prices go down and new potential applications have emerged. This paper presents modeling, simulation, and control of the power generation of a thermoelectric generator (TEG) using Matlab/Simulink. To get the aim of maximizing the power from the TEG, an MPPT controller based on sliding mode control (SMC) was implemented on a boost DC/DC converter, to ensure that the TEG operates at its peak power whatever the conditions of entry. To examine the modeling and the truthful function of the MPPT method, an HZ-20 module feeding a resistor through a chopper was used. The proposed tracker offers best performances in static and dynamic regimes comparing to Perturb and Observe (P&O) technical algorithm. The results indicate that the average efficiency of the proposed method is found equal to 98.58% greater than the efficiency attained by P&O which is equal to 96.02%.
