I am working on a project in which I need to control the duty cycle of the pulse given to mosfet in an AC to DC converter.The mosfets are connected to LCL filter to give a regualted 5V.The output voltage and a reference of 5V error is taken and a compensator is connected.The output is compared using PWM and then sent to mosfet.Do we need mosfet driver in between?What kind of mosfet driver should I use in multisim?Can I get any reference?Should we solve this using bode plot?Should I use PID controller to decrease the error and should I simulate in MATLAB using PID controller ?As I find it easy

Dear Harshini Aluwala,
Have a good day.
I suggest you to see the following article.
Conference Paper Intelligent control for the exciter of a synchronous machine...
If you have any questions please let me know.
Best regards from Mexico.

I dont understand, you use a voltage error from your reference and measured voltage to generate your duty cycle to feed into your MOSFET, that itself generates your duty cycle, but im talking from a simulink point of view, is it not similar in your software? You compare with a traingular waveform to generate a PWM waveform, right?

a useful link for the simulink environment, for this problem.
Please read my paper

I hope this helps.
