Trying to find this answer is so difficult that I can't even tell whether What is the difference between a transformer and a coupled inductor? is asking the same thing.
Some reading suggests that a "flyback" element (which may be called a "flyback transformer," may also be called a "coupled inductor?," and which may be (or always is?) part of a "flyback power converter") is at least schematically equivalent to something like a conventional transformer with a parallel inductor. Is that correct, and if so can someone provide the appropriate schematic?
Can someone provide a clear depiction of the physical embodiment of a flyback element? I can't determine what the core must look like. As far as I can decipher it consists of two independent "high-side" windings, and a low-side winding (which with a ZVS driver may actually consist of a split/dual winding).
Finally, what are the relationships between the windings, low-side current, and high-side voltage and current output characteristics?
