Hi guys! I'm working in my thesis and I need to demonstrate the application for an (galvanic) insulated air core microtransformer with high coupling factor (k). My first thought was to build a digital isolator but I don't really see the advantage of the high coupling compared to the usual devices which use medium k transformer. Some people pointed out that DC-DC converter could be a good idea but I'm not very familiarized with them.
I did some research and I see that forward converter or flyback are the best options for the design (right?)
Which one would you consider? Can you think in any other approach?
The limitation that I see is that I'm working with an air-core transformer which is probably not ideal. Also since it is a microtransformer, the whole circuit should be as small as possible to take advange of the size feature (not CMOS design though)
Thanks in advance!
