design of 700W power supply

(OP)
Hi,
hope you are doing good.
i want to design a smps with input 170-270V AC and output to be 70V 10A, 700 W DC.
while flyback converter be suitable for such application?
If not could you pleas suggest a suitable converter for 700W power rating?

Thank-you
Warm Regards
Harini Krishna

RE: design of 700W power supply

Harini; What you propose is an extremely difficult task. It's like saying, "I want to land a Boeing 747", only there's probably considerably more difficulty in designing that power supply!

It could easily take 3 weeks of study to actually conclude which topology makes the most sense for whatever task you're doing it for. Further more, it is an exceptionally dangerous task. Death lurks everywhere in that scale switching supply.

On top of all this these type supplies can be purchased for pennies-on-the-dollars you will spend designing and revising and revising and revising and revising the design. I would expect this design to take more than a man year of focused electrical engineering by a skilled power supply engineer.

Why would you subject yourself or your employer to this?
