i think there are a lot of experts in this forum, but surprisingly no one is willing to help me .. i m disappointed
 

When you say smps, I think of a buck converter. Probably interleaved multiple converters.

Questions:

a) You state an output spec of 20A. A buck converter will need to draw approximately that amount from mains AC. Do you have a mains AC branch that can provide 20A without blowing a fuse?

b) You specify a 'full bridge'. What sort of full bridge do you intend to use in the smps?

c) This project will require components that must carry both high voltage and high current. Are you able to obtain components with those specs, size the wiring, work around high V and A, verify proper operation, detect failure modes, troubleshoot, etc.?
 

I have one doubt.

In India single phase AC is 230 V , 5 A. So the total power is 1150 W.

In this thread output is 110 V, 20 A. So the total power is 2200 W.

Which converter can give 200% efficiency.

How to make this? . What type of topology we can use?
