  1. hi,
    this is pavan,presently i am dealing online ups project.In that i
    am
    using pid and pfc fuctions. in pid i get problem in using of
    compensators,any one please send me voltage compensator transfer
    fuction equation and current compensator transfer fuction
    equation.

    I have one equation............
    Gv(s)=Kpv((1+Tco.S)/Tco.S)


    here Kpv=(2K2K3/K1Km)*(Vacmax/Vacmin)*(Vacmax/Vacmin)*(Vds/
    Zfcv).

    in this ian getting problem in frequeny ..........!


    In this proj i am using 20 kz frequncy.................!

    In above eq how much freq required ,please send me
    urgently...........!!!!

    First: you've already asked this question, and gotten answers -- why are
    you asking again?

    Second: are you really, seriously, asking someone on the group to do a
    bunch of work for free, then send you the answer? There is no one good
    design for this -- if there was, then it'd be in the data sheet for the
    control chip you're using, and you wouldn't have to ask here.
