Listen to this webinar to discover how the breakthrough performance of UnitedSiC 750V Gen 4 SiC FETs ([ Ссылка ]) enables a simple design of a highly efficient Totem-pole PFC. Efficiency measurements on the developed 3.6kW unit will demonstrate a 99.3% efficiency rating. Insight into the losses is provided by the UnitedSiC FET-Jet Calculator(TM) ([ Ссылка ]) on-line tool, which are shown to match the actual measurements quite well. Finally, we discuss how the high efficiency of SiC FETs allows further BOM cost reduction for Totem-pole PFC.
