Isolated DC/DC step-up 500-750W

Other Parts Discussed in Thread: LM25037


I need to design an isolated DC/DC converter with:

Vin: 16-35V

Vout: 48V

Pout: 500-750W

and I am looking for the best topology.

I tried with Webench and it gave me two solutions: Push-Pull and Phase Shifted Full Bridge.

I ask if a non isolated Boost + LLC is good for this purpose.
