DC-link voltage controller design for grid side AC-DC converter.

[sonicbrain]

Hello,
I want to learn somethings about DC-link voltage controller design for grid side AC-DC
converter. Can someone say something about this?

Are you talking about active front end control?

 

[sonicbrain]

yes exactly

 

[sonicbrain]

Is there someone who can answer?

 

[Mr.Cool]

do you mean like having a 3-phase controlled rectifier and you change the firing angle to acheive the variable DC voltage you want?

well, at least i said something

I understand that the question is about control of an active front end with sine pwm as sketched in the below diagram.

You'll find a lot of literature under the key words "active front end control(ler)". I think it's inappropriate to retell the text books and scientic papers about the basics of this topology.
