Digital Power
2000W Digital Power Solution
In digital power AC-DC conversion, the hardware topology of PFC+LLC is used. In the PFC output bus voltage is not fixed (dynamically adjusted according to the load conditions) while the LLC operating frequency range is relatively narrow (gain curve is relatively flat), the dynamic requirements of the application, the PFC and LLC common use of a QXS320F280049, CPU0 control PFC/CPU1 control LLC
