I'm using flyback in my existing designs and it is rated at 800V currently. Wanted to design with 1.4kV input, what can be best possible solutions?

Possible solutions:

1. Use a simply front-end buck dropper and follow with the 700V/1kV flyback

2. Use a capacitor network to create a "neutral" point

3. Use a larger flyback transformer with tripple insulated primary and secondary.

What would you recommend ? or any other best solutions?
