Thermoelectric generator (TEG) is built based on Seebeck effect to convert heat directly into electricity. In the open circuit composed with two different conductors, if there is temperature difference on the two contact points of the conductor, electromotive force will come into being in this open circuit. The polarity of the output voltage depends on the polarity of the temperature difference on both ends of the TEG. If the hot end and the cold end of TEG are swapped over, the polarity of the output voltage will change.

When comparing with mechanical thermoelectric generator with DC power supply, TEG has obvious advantages.
1.There are no shelf life restrictions and no need of maintenance, so it has long service lifetime.
2.As thermopile operates stably, the supplied voltage is stable and there is no short circuit phenomenon.
3.Because of no rotation parts, this TEG is completely silent and extremely reliable.
The power of TEG is from 4.5w to 12w, which can be made into a table lamp or mobile boiler. What’s more, it has been widely used for lighting, battery charge and some other applications needing DC power supply..
