Increasing power densities, cost pressure and an associated greater utilization of the
robustness of modern power semiconductors are making thermal system optimiza-
tion more and more important in relation to electrical optimization. Simulation models
offering a combination of these two domains have not been available up till now.

Abstract
The article describes new SPICE and SABER simulation models which contain a
dynamic link between electrical and thermal component descriptions. On the one
hand, operating states in which a relevant inherent heating occurs can be simulated
under a good approximati
