    Hello all,

    I am new to Power Electronics.

    I have a simulation of Voltage Mode Controlled Buck Chopper.
    Pspice VMC Buck.jpg
    When I plot the Output Voltage I see that the feedback only corrects the error in changes to Load current and not to changes in Input voltage
    Output of VMC Buck.jpg Can anyone please tell me what I am doing wrong.

    Thanks

    Shomik.

    I think that your error amplifier has too small gain, but I will check further when I get to the computer.
