| Abstract |
This paper presents two buck converters switching at 50 MHz and based on Gallium Nitride dice. Thefirst converter features a diode designed for power applications and demonstrates 87.9\% peakefficiency. The diode mounted on the second one is aimed at higher-frequency operation and bringsthis value up above 91\% in the same operating conditions. Loss contributions are evaluated, showingthe influence of the diode alone on the efficiency of such converters. |
