Abstract in different language: This paper has been realized in order to show simplified design procedure on how to meet the standards for dc-dc converters, which are being constantly increased. The paper deals with improvement of qualitative parameters of LLC converter. Using evaluations methods Figure of Merit, we select optimal components suitable for high-frequency applications with high power density, where we want elevate the significance of perspective of semiconductors GaN, SiC and modern magnetic materials. The main advantage of using FoM assessment technique for certain system's components is the elimination of simulation and physical experiments for effectivity evaluation. In conclusion, a comparison of converter considering standards ENERGY STAR defining the efficiency parameters of the converter at different load is provided. After it also comparisons of the efficiency using diode rectifier and synchronous rectifier on the secondary site are given.
