In designing the power supply for an radiation detector, I need to supply up to 1,500V at 2 mA from mains (170 Vdc).
I've largely considered a flyback converter, but cannot find a flyback transformer with a voltage gain of N=~16 (for a voltage gain of 8 at 50% duty cycle) rated for 1,500V at the output winding.
Looked into charge pumps/voltage multipliers some, but not yet in depth.
Also just recently learned about CCFL inverter transformers, but still need some time to understand them better.
This project requires a small size and weight, so using a large transformer is not preferred.
What are other ways to step up voltage which I may look into?
