Designing a 28V --> 200V power converter

[core7916]

I need to design a circuit which takes around 28V of input and outputs the 200v with 20A. Can any one help me.

Welcome to PF.

You need an inverter.
I assume the 28 V is DC, but is the output AC or DC ?
The output will give 20 * 200 = 4 kW.
The input current will be 4000 / 28 = 142.85 amps.

What in the world are you building that requires 20 amps and 4 kW of power?? And your input amperage is more than my entire house can pull from the mains! How are you powering the input? You can't just plug this into the wall.

Your input is way above welding machines, and the output is at the level of the mains voltage.
In short: if you have to ask for help, then just don't begin at all.
Buy something ready, but be very careful even with that.

Because of the apparent lack of experience for the OP, especially in High Voltage / High Power circuits, this thread will remain closed as too dangerous.
