HIGH EFFICIENCY, HIGH POWER DENSITY

DOCUMENTATION ONLY

This reference design demonstrates the application of Wolfspeed’s C3M 650 V Silicon Carbide MOSFET technology in TOLL (TO – Leadless) package to create a 3.6kW bridgeless totem-pole PFC for server, data, and mining power supplies and telecom systems. Wolfspeed’s TOLL package offers low conduction and switching losses, which further enables smaller, lighter and highly efficient power conversion systems.

The design accomplishes

  • Peak efficiencies of 99%
  • Suitable for use in power supplies to meet 80 Plus Platinum/Titanium, ENERGY STAR , and ErP LOT 9 efficiency requirements
  • Power density of 92 W/in3
  • 60 kHz switching frequency

This reference design is offered as a comprehensive design package which can be used as a starting point for new designs with Silicon Carbide power devices.
