An Adaptive Electrothermal Model for Estimating the Junction Temperature of Power Device

The insulated-gate bipolar transistor (IGBT) module that is sensitive to high temperature has been identified as one of the most fragile parts in electric vehicles. In this article, a new adaptive electrothermal model that is independent of solder aging is proposed to acquire junction temperature in real time for the health management of IGBTs. Compared with the traditional adaptive electrothermal...
