Hello All,
I need help in designing a 84V 10A actual output supply(only one output) , a charger that operates on CV/CC mode and i dont know how and where to start from. My input is 90-270VAC@50Hz.

i tried this on webench , can i go in this way?
Oh yeah i almost forgot , yes now i got it phase shifted full bridge is really best one! . Thanks a lot sir.
sir i generated two different designs according to my calculations using UCC28180 & UCC25630 , can i merge both of them to form a final design?? I have attached both the webench links?

yes i got it. I took 390VDC@2.2A VDC output from PFC using UCC28180 and then i will interface this output to HB-LLC stage of UCC25630 as input to obtain final output of 84V@10A. But now only doubt i feel that do i have to get the output current of 10A from PFC stage at 390VDC and put same into LLC stage in order to obtain final output of 84V and 10A output? Then wouldnt it be too much to pressure on the IC for handling atleast 4000W power output to produce 840W? I am so far only using the datasheets for calculation purposes so i feel a bit stuck here also.
Yes i had a notion that LLc would scale. I m like just a noob in power management area being a college student i m still learning , the problem is i dont have any SMPS experienced people around me but this forum has helped me a lot. So now i gotta go understand and finish my calculations. Thanks a lot sir!
