文摘

: In this paper, the thermal behavior of a power transistor mounted on a dissipator is considered in order to estimate the transistor temperature junction only using a measure of the dissipator temperature. The thermal transfers between the electric power applied to the transistor, the junction temperature and the dissipator temperature are characterized by two fractional transfer functions. These models are then used in a Luenberger like observer to estimate the transistor junction temperature.
