The on-line thermal monitoring on power device appears to be an interesting issue to manage the safe operating area of converter and to prevent the ageing of the device's packaging. In this paper, authors present the technical design and the laboratory results of an indirect and an on-line Vce0 (Id sense) thermal monitoring applied to one IGBT and included in a PMSM blowing fan VSI. This converter is dedicated to an aeronautic application. An interesting outcome is the integration capability of the proposed sensor as an ASIC and afterward embedded on the driver board as a smart driver approach.
