Abstract :
This paper deals with derivation of the optimal design of high frequency transformer, which forms very important part of the dc-dc converter. Design procedure focuses on the possibilities of converter´s power density and efficiency increase. In order to meet upcoming regulation and standards for dc-dc converter efficiency, the influence of transformer´s core geometry is investigated. Precise simulation model of dc-dc converter, together with exact simulation model of transformer is used for evaluation. Finally, simulation results are provided in order to investigate the influence of core geometry on the efficiency of proposed converter.
