Hi Guys,
I have an isolated power supply which is taking a lower voltage up to 350V DC @ 200W (push-pull topology). At the moment I don't want to rely on a aux winding to power the secondary side circuitry. There isnt a great deal out there with HV isolated feedback to go by, so I thought i'd ask and draw on other peoples experience with this. I would like a self powered configuration that can be run on the HV line (with low loss). Ive seen a few examples or suggestions online with the TL431, if anyone has any suggestion with TL431, that would be great.

Thanks in advance
