Hello. I developed one using the UCC28070 PFC Interleaving with using 5KW power and core, but I'm too warm in them. I need help finding the right core for use in this PCF.Does anyone have any information of which toroidal core to use? in my research I found the core "high flux", but what size? Through the software PowerEsim I got a very large core, which I think is wrong.My personal contact is: lssouza@linear.com.brThanks
