Abstract :
A system for projecting future device temperatures in insulated metal substrate (IMS) based systems is developed. The system utilises a Luenberger observer to estimate present device temperatures from accessible temperature measurement nodes. Future device temperatures are projected from these measurements permitting feed-forward control for active thermal management. Experimental results are presented verifying the accuracy of the proposed system.
