I n an idealized diode, no reverse current flows from cathode to anode when the device is reverse-biased. However, with real-world diodes, large amounts of stored charge can flow from the cathode—back ...
A new 600V GaAs Power Schottky diode is compared with Si and SiC diodes in a 200W CCM-PFC system. With both, GaAs and SiC, the PFC system losses were reduced up to 25%. Higher on-state losses of GaAs ...
The introduction of silicon carbide (SiC) diodes has been a welcome solution to the reverse recovery losses in continuous conduction mode (CCM) boost power factor corrector (PFC) converters. While SiC ...
In Part 1 of this article we discussed electric power basics and the need for and advantages of active power factor correction. The next question should be “Okay, then how does active PFC work?” ...
