Abstract :
The purpose of this work was (a) to develop an experimental set-up which is capable to record the time dependent temperature fluctuations of single junction thermal converters due to low-frequency ac currents by using an IR photo detector and (b) a characterisation of the local and temporal temperature behaviour of shunts for the ac current measurements with a thermocamera
