Hello all,

I am new to Power Electronics.

I have a simulation of Voltage Mode Controlled Buck Chopper.

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
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.
