Hi ,
I am designing pfc front end converter for battery charger application. I have designed and selected power devices for our application. now i am in selection PFC controller .
Power level = 4 kW
output voltage = 400 Vdc
output current = 10 A
input voltage = 160 -265 Vac input

controller requirement = above 90 % duty cycle
mode : average current control mode,CCM
frequency = 30kHz


I have decided to choose UC3854A ti make PFC controller for my application ....Is that controller is good.... and shall i proceed my controller section design for my application. or can you say part number which you are proposing to use......?
PHP:
ANY FEEDBACK or SUGGESTIONS ....................
 

TI's unitrode ICs (like the one you posted) are generally good. In the past I used a UCC28070 to make a couple 20KW variable supplies, and it worked very well. It's similar to the UC3854, but has two interleaved phases, discrete kvff power limiting (lower line distortion), frequency dithering, and a couple other neat features thrown in (most of which I didn't use though).
