Structural Optimization of Electronic Devices
by
Ronald H. W. Hoppe
Institute of Mathematics, University of Augusburg, Germany

We consider structural optimization problems for technological processes in high power electronics described by the quasistationary limit of Maxwell's equations. After discretization by curl-conforming edge elements, we solve the discretized optimization problems by primal-dual Newton interior-point methods featuring the combined use of logarithmic barrier functions and simultaneous sequential quadratic programming and involving iterative solvers for the discretized PDEs based on adaptive multilevel or domain decomposition techniques. Convergence to a local minimizer is monitored by a hierarchy of merit functions within an appropriate watchdog strategy. Examples include a topology optimization problem in the design of electric drives for high power electromotors.
