Question SMPS for "isolation": 120in-->~100dc out??

Any SMPS gurus here?

Here's what I want to accomplish:

AC Line in ---> smps w/galvanic isolation--->~120vdc out (that can be anything between ~90vdc and ~130vdc (the low end is actually better). Regulation need not be terribly tight, but I need >500watt power level, up to 1000 watt is better.

Simple, efficient, and fairly easy to get the HF hash filtered out are important considerations. No problems to use an off-the-shelf chip solution or combo of standard building blocks. Can probably wind/build a suitable core/transformer (probably).

Any ideas, directions, schemes would be appreciated so that I don't have to go and become an "instant expert" and make all sorts of basic mistakes...

I haven't even seen a brick that does this, which is part of why I am considering building one for my application.

Help!!

TI parts search recommends the UCC3580 according to the your requirements. It says it's good for up to 800W. Maybe something worth looking at.
