In some applications, the design imposes system mechanical constraints requiring higher power density. With zero reverse recovery performance, SiC Schottky diodes make it possible for a power system to maintain the same efficiency while greatly increasing switching speed. The increased frequency design achieves the requisite power in a smaller physical volume (thus higher power density). The picture represents two 500W PFC boost converters. The one on the left uses a silicon boost diode switching at 80kHz. The one on the right is using SiC Schottky diodes switching at 200kHz. Both designs produce the same power and approximately the same efficiency rating. The physical size reduction is the result of smaller magnetics and capacitors associated with filtering and conditioning at higher frequencies. The comparison data shows that the higher frequency SiC design, reduces size by 38% and lowers weight by 44% while maintaining greater than 91% efficiency.
