Abstract: The purpose of this paper is to develop a high-efficiency, high-output power thermoelectric power generation technology, and to systematically study the power of this technology in the application of thermoelectric equipment under various working conditions. Firstly, the modeling, design and construction of thermoelectric modules and systems are discussed, and then the research results of a state-of-the-art thermoelectric module measuring instrument that can perform on-site real-time measurements of key thermoelectric characteristic parameters are presented. In addition, in-situ real-time characterization of a variety of thermoelectric properties was performed, including efficiency, current-voltage (i.e., I-V) curves, power-voltage (P-V) curves, external force response curves, and power versus temperature (P-T) response curves. After in-depth research and construction, a high-power thermal energy collection device has been built, and important innovations have been made for thermoelectric engineering equipment, which are well applied to the research and development projects of waste heat collection and utilization of exhaust gas thermal energy. Finally, the research results show that the simulation and calculation efficiency of the three-cascade equipment is more than 19%, and the experimental test efficiency of the two-cascade device is more than 10.6%. These results result in a significant increase in both output power and thermoelectric efficiency compared to existing technologies.
