6.6 kW High Frequency LLC

Product shot of Wolfspeed's Reference Design of a 6.6 kW High Frequency DC-DC Converter.
CRD-06600DD065N
  • Demonstration of Wolfspeed’s 650 V 60 mΩ E-Series Silicon Carbide MOSFETs in a 6.6 kW High Frequency DC-DC converter targeting high power density applications
  • The demo board consist of a DC-DC LLC topology in which primary side is based on a Full bridge stage while the secondary side is based on a asynchronous rectification stage
  • Utilization of high frequency operation allow the demo board to be smaller; lighter and overall more cost effective
  • Wolfspeed’s 6.6 kW high frequency demo board can accept 380 VDC – 420 VDC as an input and provide 400 VDC at the output with > 96 % efficiency
  • Main target application of this demo board include: Industrial power supplies and EV Chargers
  • Documentation includes a bill of materials (BOM); schematic; board layout and the application note
