Abstract

A malfunction detection device (40) is provided for a power generator (10) that includes a thermoelectric transducer module (14) including, as a plurality of thermoelectric transducers (12), a plurality of semiconductor single crystals in which the band gap energy of an intrinsic semiconductor part (12c) is lower than the band gap energies of an n-type semiconductor part (12a) and a p-type semiconductor part (12b). The malfunction detection device (40) performs a malfunction detection of the power generator (10) on a transducer-to-transducer basis. According to this malfunction detection process, the temperatures (Ti, Tn and Tp) at three points of the thermoelectric transducer (12) are detected or estimated. An estimated electromotive voltage (Vte) is calculated on the basis of the temperatures (Ti, Tn and Tp) at three points that are detected or estimated. A malfunction of the power generator (10) is detected when the absolute value of the difference between the estimated electromotive voltage (Vte) and an actual electromotive voltage (Vta) is greater than or equal to a threshold value.
