Abstract
• Thermoelectric generators (TEGs) directly generate electrical power from the geothermal/waste heat as well as contribute to efficient usage of the energy.
• TEGs cannot be operated at full capacity without additional electronic equipments, since the internal resistances of TEGs are not equal to the device resistances connected across TEGs.
• For this reason, in this paper, the application of a DC–DC boost converter with maximum power point tracking (MPPT) based on microcontroller embedded in perturb and observe (P&O) algorithm has been proposed to obtain maximum power from a newly designed portable TEG (pTEG) in a real TEG system.

Existing System
• Thermoelectric generators (TEGs) are renewable energy devices made of a semiconductor that directly convert the temperature difference between surfaces into electrical energy.
• Advantages of TEGs are silent operation, long lasting, environmentally friendly, stable work, have no moving parts, and do not require maintenance.
• However, they have some disadvantages such as low efficiency (<10%) and high cost. Their operating principle is based on the See beck effect.
• The basic structure of TEGs is formed by p- and n-type semiconductor thermo elements (TEs). • TEs are connected electrically in a serial manner to increase the output voltage of the TEG and
connected thermally in parallel to decrease the thermal resistance of the TEG.

Proposed System
• This project has presented the charging differences between a direct charging and a DC–DC boost converter with MPPT for charging a battery group of a pTEG in a real geothermal TEG system.
• Therefore, the variation of the internal resistance of pTEG being more sensitive to temperature and varying depending on the temperature difference has been taken into account.
