Abstract
	In this paper we present an efficient algorithm for the thermal simulation and design of multichannel power semiconductor devices. The simulation workflow starts with a finite element discretization of the heat transfer equation. In a second step, the resulting large system of differential equations is approximated with a reduced order model by means of the Arnoldi algorithm. The reduced order model is formulated as a state space representation suitable for the electro-thermal board/chip system analysis in a system simulation. The entire modelling process is automated and is now available for use with ANSYS-Workbench and Simplorer. We will demonstrate the modeling flow for the electro-thermal analysis of new switch devices from Freescale. The application of the method is demonstrated for simulating dynamic thermal runaway.
