3.6 kW Bridgeless Totem-Pole PFC with Synchronous SiC MOSFETs

Product shot of Wolfspeed's 3.6kW Bridgeless Totem-Pole PFC reference design.
CRD-03600AD065E-L
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 power supply, data center power supply, mining power supply, and telecom systems. Wolfspeed’s C3M™ 650 V Silicon Carbide MOSFET in a 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 80+ Platinum/Titanium, Energy Star, Lot9, and OCP3.0 supplies
  • 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.
