i am on a team where we are building inverters using different techniques like the H-bridge and centre tap technique.Actually i am the novice there.Hi,
A ferrite pot core comes to mind here. They are easier to wind too. But what are you going to use this for and how much power?
BTW 20kHz isnt that high but yes steel laminations are not a good idea.
we are experimenting on different ideas.
Any way i want to wind a 12-0-12/220V /1000W centre tap transformer that will be switched at the mentioned frequency but i cant use iron core because of high eddy current losses and other forms of losses involved with iron cores operating at high frequencies.
if you have any useful info on ferrite pot core as you mentioned i would really appreciate.
2)I am also looking at LC filters so if you have a pdf or link on how this filters are wound i will be grateful.
i do have some notes though but any addition would do.
