2.2 kW High Efficiency (80+ Titanium) Bridgeless Totem-Pole PFC with SiC MOSFET
- Documentation only. No hardware.
- Highly efficient and low cost solution of 2.2 kW bridgeless totem-pole PFC topology based on Cree’s latest (C3M) 650 V 60 mOhm 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
