Abstract

Abstract:

The power and efficiency of thermoelectric generation are not only affected by the performance of thermoelectric generator and the temperature difference between the hot and cold ends, but also by other factors under certain conditions. Therefore, the effect of series-parallel operation on the efficiency of thermoelectric generator was studied in detail by means of simulation analysis, experimental demonstration, theoretical prediction and experimental test. The series-parallel operation is divided into two types: same series with different parallel, different series with same parallel. From the study of three series-parallel operation conditions, it is concluded that there is only one condition for the maximum power value. At low temperature, the number of series is the same as that of parallel operation, and the internal and external resistance values are the same. The internal thermal resistance and the variation of thermal resistance with hot end and cold end are important factors that influence the maximum power value. The research results provide theoretical support for the application of thermoelectric generator.

Key words: thermoelectric power generation, series-parallel, power generation efficiency, load pressure
