I get good performance by extracting the core of a TV flyback, rewinding it for whatever voltage, and then driving with a full bridge. That way you are not limited to the operating parameters of the original flyback circuit. You can get 100-200 W depending on core size and frequency.

I was thinking about driving it single ended and using a transistor circuit to detect when the protection diode is conducting and when the inductive surge starts and stops.

I can detect that signal with a microcontroller so I can drive the transformer with an asymmetric signal to get the maximum possible duty cycle at the output while preventing excessive currents through the primary.

I don't know if it actually works though.
