Designing a 48VDC to 30VDC 3A isolated power supply

Hm, I wonder if that was short lived then?  My 500W PSU is this type, but it's also over 5 years old I think.

Also a good candidate for that configuration (PFC stage), resonant.  Not sure if they're using them though.  Cross regulation on multiple outputs might be a problem (that's one feature of forward converters, the transformer and multiwinding choke both serve to equalize outputs).
