2.2 KW, High Efficiency (80+ Titanium) Bridgeless Totem-Pole PFC with CREE’S (C3MTM) SiC MOSFET (TO-263-7)

Categories // Latest News Power

CRD-02AD09N by Wolfspeed - Silicon Carbide Test/Evaluation Products

This reference design includes Wolfspeed's C3M™ 900 V SiC MOSFET and enables users to comfortably achieve Titanium standard by having 98.5% efficiency and input PF greater than 0.98, while THD is less than 5% under all load conditions. The reference design includes schematics, BOM and PCB layout.

Features:

  • Highly efficient and low cost solution of bridgeless totem-pole PFC topology based on Cree’s (C3MTM) 900 V SiC MOSFET in a TO-263-7 Package
  • Comfortably achieve Titanium standard by having 98.5 % efficiency while THD < 5% 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
  • Documentation includes bill of materials (BOM), schematic, board layout, application note and power point presentation
