We are designing None- DC DC Converter with parameter as below
- INPUT Uin=300VDC - OUTPUT: Uout= 110VDC, Iout= 150A
We wonder how to choose suitable DC DC topology. Sync-buck is ok ?

Thanks in advanced!

P/s the privious have been move wrong forums :D

The reply your received on your other thread is correct--for an output power of 16.5 kW, you really need to move to a topology that is capable of delivering that much power. This is the phase shifted full bridge topology. This topology is frequently isolated but does not have to be.

I would not recommend sync-bucks as you would need to parallel many of them to effectively get the 150A out.
