Abstract

This paper presents the results of investigations on three types of high frequency transformers with different magnetic and winding configurations for the switching resonant mode power supply. The experimental results demonstrate the characteristics of self inductance and voltage ratio versus frequency. The magnetic flux and eddy-current distributions of Pot core, Planar core and multi-element core transformers are calculated by a CAD/CAE software package which employs boundary element method technique. Both experimental and computer modelling results are used for optimum design of high frequency transformers and minimising the copper losses in transformer windings
