Topology selection

Hi Team

My Design inputs:

input voltage range 1:- Vin min:316 Vdc, Vin nominal:587Vdc, Vin Max: 815Vdc

input voltage range 2:- Vin min:417 Vdc, Vin nominal:700Vdc, Vin Max: 1000Vdc

input voltage range 3:- Vin min:417Vdc, Vin nominal:800Vdc, Vin Max: 1200Vdc

output remains common for 3 diffrent input voltage range

Vout:48Vdc

Iout:13Adc

Pout:626W

Application:Fan power supply

Can you please suggest me which topology is Preferable and can I use PSFB full bridge for this wide range of input.

suggest me the best switching IC.
