2.2 kW Bridgeless Totem-Pole PFC

CRD-02AD065N

Download Design Files

Highly efficient and low cost solution of 2.2 kW bridgeless totem-pole PFC topology based on Wolfspeed’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
