Term of the day : 'Silicon Carbide Schottky Diodes'
SiC Schottky diodes have essentially no reverse recovery current, and the minimal amount of capacitive current present in turn-off is independent from temperature, forward current, and di/dt. This results in virtually no switching losses for the rectifier and substantially lessens switching losses in the switch. The use of silicon carbide diodes in the pfc circuit (as in TDK-Lambda's NV-Power range of power supplies) can offer around 4% efficiency improvement.
