Hi There,
I ran across this: http://www.pes.ee.ethz.ch/uploads/tx_ethpublications/biela_DCDC_INTELEC07.pdf
and was fascinated with such amazing power levels from a small SMPS. But upon reading it, and looking at the pictures of the completed unit, I was lost as to what/where the primaries and secondaries were as well as where the core is located. It appears to be just a big block of copper, yet has all the components forming a huge transformer. And, this 5 to 10KW beast of a supply fits in a 1U height chassis!!! (That's just 1.75 inches high) Really? How?
I've built some pretty huge switching supplies before, but never anything that looks like this beast! So I defer to other's on this forum with much greater knowledge than I to see if you can explain this supply in layman's terms so that even humble-ol' me can understand.
Thanks for your help on this. And certainly, anybody is welcome to add their comments on this. Maybe if we pick-it-apart enough with each person adding a little piece of the puzzle, we can still figure it out!
Please throw in your comments and ideas! And thanks everyone for making this such a great place for SMPS knowledge and projects!
P.S. I've attached a copy in case something happens to the link down-the-road.
