Hello nice to meet you! I'm here because I'm having trouble calculate about full bridge converter so if I can get help from you.
I'm wondering how to get R and duty when Vin=800V, Vout=14V, P=5kW, fs=50kHz
I'm sorry just asking calculate but I will try study hard so I can help others in the future too. Thank you for reading!!

5000-Watts at 14-Volts = ~357-Amps.
Are You sure the 14-Volt Winding needs to supply that much Current ?

Do You have a Schematic, or at least a Block-Diagram ?

First,
Do You have a Transformer capable of 5000-Watts,
with enough space for the huge 400-Amp rated Wire that You will need for the Secondary Winding ?

The Choke will be almost as big as the Transformer.
