Highly efficient and low cost solution of 2.2 kW bridgeless totem-pole PFC topology based on Cree’s latest (C3M™) 650 V 60 mΩ SiC MOSFETs

Comfortably achieve Titanium standard by having >98.5% efficiency while THD <4% under all load conditions.

Innovative resistor based current sensing solution

Distortion less inductor current at zero crossing during all load conditions

Reduced Bill of Material (BOM) by the use of general purpose diodes in place of low frequency switches

Main target applications of this demo board include: Server, Telecom and Industrial power supply units (PSU)

Documentation includes bill of materials (BOM), schematic, board layout, application note
