Abstract

A thermoelectric equipment (TEE) is constituted of heat sink and thermoelectric generator (TEG), and other components. The dynamic model for both heat sinks and TEGs are built up. Then the TEE´s equivalent circuit model is gotten. Its source response characteristic and load response characteristic are analyzed. The results indicate that the output response for heat source step signal shows a large inertia characteristic, but that for load step signal shows a little inertia characteristic. In addition, load fluctuation will also affect the stable value of the output voltage, because it will change the temperature difference between two sides of the TEG. A saber simulation model and a prototype are built up, the simulation and experimental waveforms are agreed.
