FOR INPUT RANGE 180-265VAC POWER 3000W OUT PUT 390V DC WHICH FREQUNCY IS SUITABLE ?

ANY ONE KNOW WHICH MATERIAL FOR CORE INDUCTOR CAN WORK ON HIGH RIPPLE CURRENT I HAVE 17A RIPPLE AND 10.5 RMS I LIKE USED PQ4040 TRANSFORMER CORE BOUT TEMP GO UP TO HIGH IN CORE HOW CAN CALLCULATED POWER LOSE ON CORE ?

MY PROBLEM IS I HAVE 400MM*700MM*400MM SPACE FOR 2 PCS INDUCTOR AND RISE TEMP AROUND 40 DEGREE I HOPE ANY ONE CAN GIVE ME ONE SLOUTION

    Hello Omid,

    I recommend that you run the calculator tool at say 50kHz and 100kHz.

    This will calculate an inductance value as well as a peak current and RMS current.

    Then you should contact a magnetics component manufacturer such as Wurth Electronics and ask them to size an inductor with these ratings.

    PFC inductors for the UCC28070 are usually either of feerite or iron powder. 

    Ferrites tend to have a better volumetric efficiency but tend to run hotter because of the enclosed winding.

    Toroids tend to be bulkier but run cooler because the winding is exposed to the cooling air.

    Finding the best solution to your application involves evaluating the result of initial designs and test experiments.

    Regards
