Evaluation board 3300 W 52 V LLC with 600 V CoolMOS™ CFD7
This converter is a complete Infineon solution for a 3300 W LLC DC-DC converter from 400 V to 51.5 V achieving 98.1 percent peak efficiency.
The achieved power density is in the range of 4 W/cm³ (66 W/in³), enabled by the use of SMD packages, stacked magnetic construction and cooling solution. This DC-DC converter proves the feasibility of HB LLC as a high-efficiency topology for 3.3 kW converter, at the level of full-bridge LLC or dual-stage LLC.
Summary of Features
High efficiency and high power density
Novel integrated magnetics structure
Full digital control
Graphical User Interface (GUI)
Configurable variable output voltage
Benefits
Best performance HV and LV power devices
Full or nearly full ZVS in all load range
