Other Parts Discussed in Thread: UCC25600

Hi All,

I have to design a  2 swicth forward converter for a power level of 420W.

Input : PFC DC Bus ( 370v -400V DC) and Output = 24@17A

Which one could be ideal PWM controller ?

How to design a transfomer for the above application? Does anyone has the reference design /material at this power level.

Does anyone has the step by step procudure for the design. ?

please suggest. thanks.

    For this power level and output voltage, the LLC resonant converter will be the best choice, if there is no requirement on the output to be current source when it is shorted.

    Please refer to UCC25600 product folder for the design guidelines and tools. a 300W 12V 25A outptu EVM is available
