Energy is developing from renewable sources nowadays, becoming essential research criteria. As a result of pollution and climate change, energy prices are rising, and we must also deal with rising electricity prices. To minimize these problems, researchers are currently working on optimizing energy producers that use energy harvesting. Using the Seebeck effect, thermoelectric generators (TEGs) have proven capable of generating electricity from heat directly. They do not require toxic substances, mechanical structures, or rotating parts since they are manufactured on silicon, polymers, and ceramic substrates. Present research work focused on generating power from waste heat emitted from automobiles. Copper nickel-based TEG was adopted for the present simulation work. Using Ansys 2020R1, a numerical model incorporating Thomson, Seebeck, and Joule's heat was created to check the Voltage, current, and power at different temperatures. Hot gas emissions at different temperatures from 250 to 400 °C at a step of 50 °C raising with different Reynolds numbers were investigated. A study of the overall efficiency of the electrical system was also conducted. The passive heat sink's heat transfer surface and forced air circulation significantly impacted total heat flow, preserving the system's high electrical efficiency. Using a TEG system to simulate a single-phase inverter provides real-time information about the system's power characteristics. These observations may serve as a starting point for improving the efficiency of an actual TEG-inverter hybrid system's co-design.
