    I have some difficulties regarding implementing control algorithm for inverter.
    1) I studied attached paper.
    2) I tried implementing algorithm of figure 10(b) in that.
    3) But, when i connect 270ohm resistor at output, voltage is not remaining constant.
    4) I am not getting where i am going wrong.
    I have following doubt in same.
    a) K(s) is PI controller gain?
    b) Io is total output current?
    c) do we need R in that, if i have io sensed directly?
    d) Is it necessary to use PI controller?
