Abstract

The concept and hardware and software tools for automated measurement of thermoelectric parameters of semiconductor energy converters have been developed. The system is built on the basis of advanced vacuum methods of direct measurements using a modern element base, high-precision analog-to-digital converters, which, in combination with software methods for processing the obtained experimental data, made it possible to increase the measurement accuracy. A precision software-controlled current stabilizer has been developed, which allows measuring the electrical characteristics of thermoelectric energy converters in a wide range of loads from units of microamperes to several amperes. The possibility of automated diagnostics and determination of operational parameters of semiconductor thermoelectric energy conversion modules, in particular thin-film ones, has been implemented, which makes it possible to reject defective modules and in general significantly increases the reliability of thermoelectric generators.

Experimental studies of a series of generator thermoelectric samples with known characteristics have been carried out and the effectiveness of the developed tools has been shown using the described methods for analyzing experimental data.
