As AI scales, a greater lens is on the upstream power sources that are expected to keep up with rapidly expanding data center deployments. Amperesand is helping build the cornerstone of tomorrow’s grid by developing highly reliable, medium voltage (MV) SiC-based solid state transformers. Read more to learn how Amperesand and Wolfspeed partnered to make it happen.
2.2 kW Bridgeless Totem-Pole PFC
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
