    Component values on 2-pole 2-zero compensation

    Hi guys,

    I'm trying to build a 2-pole 2-zero compensation for a full bridge dc-dc converter. I'm using sg3525 as IC.
    To build the compensation network I'm following the instructions on power supply cookbook but there are two resistors which I don't know how to calculate these 2 resistors and the book isn't showing also.

    Re: Component values on 2-pole 2-zero compensation

    For practical purposes, the transfer function of this circuit is simplified to the op amp inverter topology, so the gain would be defined as ((1/sC2 + R2) // C1) divided by ((1/sC3 + R3) // R1).
    For sure, too much algebraical handling should be made to factorize polynomials from numerator and denominator into the form (s+z1).(s+z2)/(s+p1).(s+p2).
