I am not sure if this is the right forum to post in.

My question is about the L4891 PFC controller, Is there any calculator for extracting the inductor value, and all other values?
Its going to be a very complex tast to do it using the formulas.

I have seen many other controllers comes with these powerful tools. And I don't know why ST don't have it.

Also, Is it possible to replace the MOSFET power switch with IGBT?
