Critical component's figure of merite influence on power supply unit efficiency

Abstract

The paper deals with FoM parameter analysis of power semiconductor system's components. This parameter can be used as optimization tool of quality indicators for power supply systems. The main advantage of using FoM assessment technique for certain system's components is the elimination of simulation and physical experiments for effectivity evaluation. This paper consist of description of FoM assessment process for perspective converter structures, for various working conditions and the appropriateness of using this method is also verified by simulation experiments on models with high degree of validity. The relevancy of FoM parameter is finally evaluated in the way of efficiency (one of qualitative indicators) investigation of proposed LLC converter, where also different materials of core transformers have been verified, as well as their influence on the efficiency.
