Standard SMPS (cip 'bi-directional' DC-to-DC conversion) techniques but with special attention to accommodation of high input EMFs...

Be advised, however, that the width of the stated input range entails formidable design challenges...

Yes: with extreme care. Those voltages can KILL you!!

 

Where can you get 2000VDC.

If you cannot design a circuit that uses 2000VDC I suggest that you stay away from making one that any other had designed.
You do not understand the risks involved if you were to make a tiny mistake.

 

By any chance, is that a typo, and do you mean 50-200 VDC input? I have a bit of experience with design of switching supplies from my previous job, but still wouldn't dare advise on a design over 400 volts input.

 

@Roderick Young
Do you by any chance has a design to make a SMPS operated from main that can output around +,- 28V to 40V. Around 300w or so.

I'll reply in a private message to keep this thread from drifting. Short answer, no.

 

research high voltage IGBT and BiMOSFETS. Infineon and Mitsubishi Electric specifically.
a switching bridge and step down transformer would be the way to go.
2000 ? volts. wow! what is the source of this wide ranging input? Solar?
