Tóm tắt

Emerging needs in the automotive area are being turned toward a decrease of design times of power converters. The purpose of this paper is to present a global methodology to design power electronics equipment. Instead of solving each step successively, all problems are taken into account simultaneously. The main difficulty consists in evolving simple analytical (or semianalytical) models for the different phenomena. After implementation in a Matlab/spl reg/ environment, the design consists in solving an optimization problem, under constraints. This paper compares several model accuracy, as well as various optimization methods in the case of a 42V-14V DC-DC converter.
