SOME ASPECTS OF OPTIMUM DESIGN OF ELECTROMAGNETIC DEVICES

A new method of designing electromagnetic devices especially high‐voltage ones, is presented. As a result of applying a sequential quadratic programing algorithm and a very effective algorithm for non‐linear minimax optimization, a flexible method for computer aided design of high‐voltage and semiconductor devices has been obtained. The minimax algorithm is based on a successive linear approximation of the functions defining the problem. In each iteration step these functions are computed with the aid of the finite element method. The resulting linear subproblems are solved in the minimax sense subject to the linear equality and inequality constraints. Applications of these two methods for the designing some parts of the high‐voltage devices are presented.
