Multi-Objective Optimization Platform of AC-DC Converters Components

The paper presents application of two selected algorithms for an online platform for multicriteria optimization of AC/DC converters. The purpose of the platform is to speed up selection of components to satisfy the four main objectives in power electronic circuits: total power loses, weight, volume and total price. The system generates a pareto front for the objectives considering several constraints. It uses a discrete optimization scheme searching the database of available components. The database of components contains magnetic elements, semiconductors and capacitors used in a few typical configurations of AC-DC converters. The paper focuses on presenting a concept of the system which allows to put together simulators of different components calculating objectives with modern multicriteria optimization algorithms (NSGAIII, SPEA2). The system proved to be very effective even for large databases of components composed of tens of thousands of items.
