Wolfspeed Silicon Carbide Test/Evaluation Products CRD-06600FF065N-K

6.6 kW High Power Density Bi-Directional EV On-Board Charger This reference design demonstrates the application of Wolfspeed's 650V C3MTM SiC MOSFETs to create a high power density electric vehicle (EV) on-board charger (OBC). This design leverages the high frequency switching capabilities of Wolfspeed 650V C3MTM SiC MOSFETs to create a smaller, lighter and cost effective system. This reference design is offered as a comprehensive design package which can be used as a starting point for new SiC designs. The design accomplishes: Peak efficiencies of 96.5% Power densities of 53W/in^3 or 3KW/L Specifications Universal single phase input voltage between 90V and 265V Output Voltage of 250V-450V DC 18A Output Current in charging mode Front End AC/DC PFC using CCM Totem-Pole Bi-Directional Topology operating at 67Khz Bi-Directional DC/DC CLLC resonant converter operating at 148-300KHz Constant Current, Constant Voltage or Constant Power Mode Unique integrated heatsink design removes heat from MOSFET’s, transformer and inductors CAN Interface Applications EV On-Board Charger
