| Outline of Final Research Achievements |
In order to realize the compact and light-weight highly efficient SiC/GaN power device DC-DC converter with a bottle-neck issue on the magnetic core for high frequency reactor and transformer, a novel heat resistant Fe-based metal composite magnetic core with small iron loss at MHz band was developed. The composite magnetic core consisting of 2.6 um size Fe-based amorphous powder with a thermally oxidized surface layer and 200℃ resistant epoxy resin binder exhibited 1/3 smaller MHz band iron loss than that of a bench mark core of Ni-Zn ferrite. The gapless leakage transformer using the Fe-based amorphous composite magnetic core was applied to a GaN power device MHz switching LLC resonant DC-DC converter. The novel magnetic core transformer operated in MHz switching resonant converter with a rating power of 120 W had an efficiency of 97% over and a power density per unit core volume of 90 W/cm3.
