friends I am thankfull to all of you for your valuable suggestions .
Friends we are using an inductor for this buck converter is as follows:
Core EE10028
Inductance:150uH

1-Who is the core manufacturer?
2-How many turns?

High power electronics is often operating in a 3 to 10 kHz range, dictated by a switching loss trade-off. E.g. most motor inverters in the higher kW range. They involve audible noise, if it's bearable depends...

Though keep in mind that the audible whine from a motor inverter is probably drowned out by the noise from the motor itself. Not so for a battery charger...

For the requested low voltage and power range, switching frequencies above 20 kHz should be however feasible.

Agreed, 20KHz is perfectly fine even at 5KW per phase, if you design things well. I would only go multiphase if very high efficiency is desired.
