2.2 kW Totem Pole PFC
This 2.2 kW Totem Pole demonstrates the capability of Wolfspeed C3MTM SiC MOSFETs in new low-inductance packaging to cut losses and simplify designs. Targeting 80 Plus Platinum and 80 Plus Titanium standard server power, the PFC delivers a 1% increase in system efficiency when compared to existing silicon interleaved PFC boost circuits, while also increasing power density by 15% and lowering overall system BOM cost.
6.6 kW High Density On-Board Charger
The 6.6 kW Bi-Directional On-Board Charger (OBC) targets high-power-density, high-efficiency on-board charger applications. The system delivers 54W/in3 power density and exceeding 96.5% in peak efficiency with 67kHz switching frequency for CCM totem pole PFC and 150kHz-300kHz for a CLLC resonant converter.
6.6 kW 1MHz DC/DC Converter
The 6.6 kW Full-Bridge LLC DC/DC converter targets high-frequency, high-efficiency and high-power-density applications such as on-board chargers and bus converters. Benefits of high-frequency operation include smaller magnetics and EMI filters, and higher power density.
300 kW Three Phase Inverter featuring the new XM3 Power Module!
This 300 kW Three-Phase Inverter is designed to demonstrate how Wolfspeed’s C3M SiC MOSFETs in new low-inductance power module packaging can cut losses and simplify designs. The inverter has >2X the power density of comparable Si based designs and >98% efficiency. The design features XAB450M12XM3, 1200 V, 450 A half-bridge power module in Wolfspeed’s next generation package and optimized gate drivers with built-in protections.
150 kW DBT Fast Charger
Wolfspeed SiC MOSFETs and Schottky diodes are used in this fast charger featuring two Wolfspeed system designs that deliver up to 95% efficiency: PFC Stage – Vienna Rectifier and DC/DC Stage – Full Bridge LLC.
