Generator modules of segmented thermoelements

Physical factors affecting the efficiency of segmented generator thermoelements are analyzed. The optimal control theory are used for development of a sufficiently precise method for a computerize design of generator modules of segmented thermoelements. The optimal thermoelectric parameters of BiTe-based materials for single- and double-segmented thermoelements are determined. The experimental generator samples have been made of such materials and their characteristics measured. The efficiency of modules of double-segmented legs has been found to be about 7.5% and exceed the power efficiency of homogeneous material generators.
