I'm working on a DC/DC converter (power supply) that has to go from 500V DC to 50V DC.
What would be a place to start for designing transformer for it - what kind of core material and shape to use for best efficiency - what frequencies are better 50KHz or 200 KHz or 500 KHz or more?
It seems that prebuilt transformers like that are not on the market - i.e. DigiKey does not yield anything useful.
On top of all other requirements - it has to be very FLAT - no more then 25-30 mm.
I understand that I'm looking for a kind of Holy Grail of SPSUs, but still dare to ask
p.s. if this is the wrong forum would love to be directed to the right one for such a question
