2.2 kW Bridgeless Totem-Pole PFC

Product Shot of Wolfspeed's Reference Design of a 2.2 kW High Efficiency (80+ Titanium) Bridgeless Totem-Pole PFC with SiC MOSFET
CRD-02AD065N
  • 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
