Abstract
AbstractMeasurements of assembled thermoelectric (TE) modules commonly include investigations of the module output power versus load resistance. Using an AC electrical measurement for TE modules, a model of equivalent passive RC circuit has been developed and tested for both the thermal and electrical characteristics of the module. In this work we present and analyze data of a commercially available module, using equivalent passive RC circuit, to examine, explain and model the electro-thermal activity in the module. In addition data we analyzed by thermal quadrupole theory. Measurements were taken over the frequency range of 0,5mHz to 50 Hz and the device performance (ZT) was evaluated from measured data.
