EVAL_3KW_2LLC_C7_20 3.0kW dual LLC evaluation board
Overview
The 3kW dual phase LLC evaluation board is an example of a complete Infineon solution for the HV DC-DC stage of telecom rectifiers and industrial SMPS aiming to the highest efficiency and reliability standard levels. The combination of state-of-art 600V CoolMOS™ C7 superjunction MOSFET (IPP60R040C7) in TO-220 and 150V OptiMOS™ 5 (BSC093N15NS5) in SuperSO8 power device technologies with optimized driving and control techniques using Infineon components allows to achieve this result.
Summary of Features
- Dual phase LLC topology with full digital control (including current sharing and phase shedding)
- Prevention of MOSFET body diode hard commutation and LLC capacitive mode operation
- Graphical user interface (GUI) for parameters setting and monitoring
Benefits
- Peak efficiency >98.4%
- Flat efficiency plot from 10% to 100% load
- Flexible design adjustment and fine tuning through the GUI
Potential Applications
Telecom rectifiers, industrial SMPS and high power battery chargers
