Here are the requirements, which I'm facing: Nominal output: 20V, 25A. Overload output: 10 to 20V, 60A. Overload lasts for up to 2 sec. Input: 110VAC no PFC The output powers a DC motor, so the regulation doesn’t have to be very precise. Any suggestion, insight or reference is really appreciated! Cheers, - Nick

Click to expand... LLC will give you the overcurrent you need, just need some biggish fets in the half bridge - which are readily avail now. Regards, Anna.

Do you actually need isolation? If not, you may not need a fancy DC-DC converter (though you likely will want active PFC on the input).
