Abstract in different language: The paper focuses on a selection process of boost diodes for Active Power Factor Correctors (APFC) based on the Boost converter. The choice of the suitable boost diode plays crucial role for an efficiency of APFC. The main aim of the paper is devoted to theoretical and experimental comparison of the diodes. We have compared two ultra fast silicon diodes optimized for a Continuous Conduction Mode (CCM), soft-switching ultrafast rectifier and silicon carbide Schottky Barrier Diode (SBD). The experimental results show that the conduction losses are very similar but the switching losses are grossly different. In one case the diode optimized for soft-switching was not able to properly operate above 200W input power. It was caused likely due to the corrector works under CCM operation. Whereas, the SiC Schottky Barrier diodes are suitable for application in APFCs with high switching frequencies and working under CCM thanks to very small junction charge which is proved by this study.
