Hello, can you send me derived small signal ac modeling transfer function for dc-dc converter to my email id satish_kmr143@gmail.com

please its urgent. thank you

Christain,

Its a type III compensation, with two poles and zeros placed coincident respectively. It is placed in such a way to have enough phase margin for better stability and to minimize the effect of maximum phase lag due to Right-Half plane zero.

There are many literature on type-III compensation for dc-dc boost converter.

I don`t get it :( I know how you get the state equations, but I don`t understand how you develope the transfer function of the controller out of these state equations. Thank you for your support.

Christian,

I derived the small-signal ac modeling transfer function for dc-dc converter.

Hello, how do you receive the transfer function of the controller?
