Applying expert systems and fuzzy logic for core selection for high frequency power transformers

Abstract

A large number of factors go into core selection in the design of high frequency power transformers. An experto-fuzzy system called CoGSA (Core Geometry Selection Aid) has been developed to aid the magnetic designer in selection of a core geometry. The system is based on expert system and fuzzy logic techniques. The various decision components (power, cost, shielding, heating, power density etc.) are taken into account in the form of IF-THEN statements. The fuzzy logic is applied to take into consideration the uncertainty involved with the various factors.<>
