A Guide to Flyback Transformers | Coilcraft

The duty cycle of flyback transformers typically does not exceed 0.5. Various combinations of turns ratios and duty cycles can be used to achieve the required output voltage according to this equation: V out = V in * (N s /N p )* (D/ (1-D)) where: V out is the output voltage. V in is the input voltage. N s = secondary turns.

High voltage MOT VS flyback whats more dangerous?

 · MOT make like 2KV at like 1A a flyback will make 25KV at a couple hundred MA. I understand both are dangerous, but it seems some people that mess with flybacks seem to think you would get more an RF burn than a real shock. High voltage at low current is less dangerous than high voltage at high current. The oddest thing I find with this is based ...
