    suggest PFC controller.............?

    hi,

    we are going to design a front end PFC converter for our UPS application.
    We decided to go BOOST converter for our application . the power level of converter is 8KW.....

    we have seen ti make UC3854A controller ,but there is no OVP protection in that.. suggest a list of PFC controller (any make),for our application which meets below spec.

    power converter = 8kW
    switching frequency = 20-50kHz
    protections = OVP,OCP
    topology = BOOST
    MODE =average current control

    Re: suggest PFC controller.............?

    The first and only PFC controller I've used is the UCC28070, for a couple custom 20KW, variable output PFCs I made. It has a couple fancy features (two interleaved phases, discrete kvff adjustment), but it also fulfills your specs fine. I was actually surprised at how easy it was to get running.

    edit: whoops, old thread, whatever
