    compensators,any one please send me voltage compensator transfer
    fuction equation and current compensator transfer fuction

    I have one equation............

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

    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

    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.
