Outline of Final Research Achievements |
In this research, a prototype 200 W and 100 kHz GaN FET flyback converter was constructed and tested. Experimental results demonstrate that the parallel-connection of the GaN FETs is effective to reduce the loss. From the experimental results, loss in the flyback converter with the parallel-connected GaN FETs is reduced by 0.9 % as compared to that in the flyback converter with the single GaN FET.
