     thermoelectric generators (tegs) are increasingly employed in large-scale applications, therefore accurate performance data are necessary to permit precise designs and simulations. however, there is still no standardized method to test the electrical and thermal performance of tegs. this paper presents an innovative test system to assess device performance in the “real world.” the fixture allows the hot temperature to be increased up to 800°c with minimal thermal losses and thermal shock; the clamping load can be adjusted up to 5 kn, and the temperatures are sensed by thermocouples placed directly on the teg’s surfaces. a computer program controls all the instruments in order to minimize errors and to aid accurate measurement and test repeatability. the test rig can measure four tegs simultaneously, each one individually controlled and heated by a maximum electrical power of 2 kw. this allows testing of the effects of series and parallel connection of tegs under mismatched conditions, e.g., dimensions, clamping force, temperature, etc. the test rig can be employed both as a performance evaluator and as a quality control unit, due to the ability to provide nonparametric testing of four tegs concurrently. it can also be used to rapidly characterize devices of different dimensions at the same time.
