Does anyone know of a good link to basic transformer design? I keep seeing the standard equations but they don't seem like much help. I can't seem to find any good guides for designing the most basic transformer For example, I will see equations relating the ratio of turns to the ratio of voltages, but does that mean I can go from 1 turn to 2 turns instead of 100 turns to 200 turns? I don't think that is the case. Again, a most basic guide would be good, one that assumes no losses, etc is fine.
