Using a phenomenon called Seebeck effect, thermoelectric generators convert heat energy into electrical energy. Seebeck effect is the process of generating electric current through thermocouple and keeping the intersections formed by two different metals at different temperatures. It is effective up to 5 to 10 percentage points. Radioisotope thermoelectric generators and automotive thermoelectric generator are also used for various purposes.

These generators are used for various applications such as male internal combustion engines and the pound sterling. The internal combustion engine, which produces more waste heat is mainly used in this application. The harrowing problems that appear in such an application to negative output resistance and thermal properties.

These generators work the same way as an engine-driven generators to produce electricity, but the difference between these two products are the first very still while the latter gives an annoying sound. This is because TE generator produces electricity without any movement of its parts, other than a fan.

This revolutionary engine temperature of the burner flows many a thermo electric device in the direction of the cooler where the temperature is cooled. Then this air is expelled to the surrounding air of the air-cooled fin fan which is the only moving part. A tension is created in the generator by the thermal flow of thermal energy.

High performance crystalline semiconductors are used in these generators, because the thermal power provides a very high voltage across the thermocouples and generates high voltage circulations of the primary ring.

TEG is highly reliable due to its strong structure. This is used in many military and aerospace applications for several years. It is because its main feature, with power concentrated or consolidated to a large output to maintain many applications running at the same time. The patented internal circuitry, the generated power is converted to effective stress is the main function in this. Several companies began using this device.
