hello. I developed one using the UCC28070 PFC Interleaving with using (5KW/39KHZ with input voltage:180-240Vac) power "E" core, but I'm too warm in them. I need help finding the right "toroide" core for use in this PCF.Does anyone have any information of which core to use? in my research I found the core "high flux", but what size? Through the software PowerEsim I got a very large nucleus, which I think is wrong.My personal contact is: lssouza@linear.com.br
LeonardoThanks
Hello, in my designs I typically use outside design houses to design the magnetics for my design. You might try Wurth, Cooper or Vitec to see if they have anything that fits your need or they can custom design something for you. You also might try researching the elab design center to see if anyone had done a reference design using the same power levels. http://www.ti.com/lsds/ti/analog/powermanagement/reference_design.page
Matgnetics Inc may also be a good resource to find out what the best core is to use your design. http://www.mag-inc.com/
