We are using LLC half bridge topology for designing a DC DC converter from 400V to 220V dc using UCC256303.
The power level is 2 kW for my purpose.
1) Whether it is suitable with halfbridge topology? Since Iam not seen any reference designs above 1 kW with LLC half bridge topology.
2) My output voltage is 220Vdc. Is this possible with LLC circuits? Since Iam not seen any design examples or calculators supporting dc dc outputs above 90Vdc.
If possible can you suggest any reference design for this. Iam more concerned about the output feedback portion.
