The most important are thermal conduction through the supporting membrane and contact resistance. Analytical analysis shows that each parasitic decreases device performance, but only the contact resistance creates a significant shift in the optimum device current where the temperature reduction is maximised. To obtain an energetically correct lumped-element model, as presented in this paper, the electro-thermal Peltier effect must be linked to the thermo-electric Seebeck effect, which acts as a feedback parameter. The influence of this Seebeck voltage on a non-ideal current source, driving the Peltier device, is investigated and it is shown that the influence can be ignored if the current source has a reasonable impedance. |  | View paper | | ISBN: | 0-9666135-7-0 |
