Dynamic thermal simulation applied to automotive electronics

Automotive electronics face significant problems when dealing with power dissipation. The engine compartment of a vehicle, for example often contains high localised temperatures, which escalates the possibility of circuit failure. This paper presents a technique to solve a dynamic thermal analysis problem. The engineers at Rover Group Ltd., successfully use a simulator in conjunction with system modelling blocks and macro modelling techniques to predict the behaviour of an ignition coil circuit suffering from device self-heating
