Karakterisasi Unjuk Kerja Termoelektrik Generator Tipe 10w-4v-40S Berdasarkan Variasi Susunan Pada Perbedaan Suhu Rendah
ABSTRACT
Technological developments as well as population growth led to an increase in
electricity sources. The dependence on a large percentage of electric energy
sources will cause a future electricity crisis, thermoelectric generator (TEG) is the
right alternative energy development tool as a converter of wasted heat energy
into electrical energy. However, recent research has focused on developing high
efficiency that requires high temperatures. Application at high temperatures can
affect the value to effectiveness (efficiency) caused by heat penetration. This
paper will show the characterization of the performance of the TEG element type
10W-4V-40s at low temperature differences, where the low temperature is the
cold side of the TEG element at room temperature which is easy to create. The
selection of this low temperature aims to reduce the effect of heat penetration.
Characterization was carried out against two elements of TEG with the aim of
comparing output voltage, power, internal resistance and efficiency of TEG
elements. Measurements on a single element of TEG taking into account the
absence of heat penetration are able to increase the output voltage, then the results
showed internal resistance to TEG of 1.2 Ω more stable, with a figure-of-merit
value of 0.73 and efficiency of 0.87%. Moreover, two TEGs connected in series
can increase the output voltage by converting efficiency by 1.4%, while the
parallel circuit can increase the output current by only 1.25%.
