Hello everyone,
I'm new to this forum and high voltage SMPS, therefore, i'll need your help with my 700W SMPS +-35V. I have read some of the threads and i really liked the proposed projects.
For my project, I have found a website that can help with designing the SMPS (poweresim) and for my specs, they recommend a flyback AC/DC smps using the following design:
According to their charts, this is the best SMPS configuration since power dissipation is around 70W with an efficiency of 84%. I have attached the poweresim file that can be uploaded to their website to view the design and the charts.

Can you guys tell me if really this design is good before i start building it? I'm somehow skeptical about flyback SMPS since i have read on nxp's site (http://www.nxp.com/documents/application_note/APPCHP2.pdf) that these power supplies are suited for 200W low input voltage circuits.
Thanks for your help
