flyback transformer turns ratio
It has me puzzled how exactly do you work out the turns ratio of a flyback transformer?
its not sinusoidal waveform afterall, more like crazy pulses.
I'm just not getting the loaded secondary voltage I want with my experiments.
I'm doing a step up from 12V to 30V, unloaded the secondary does have huge voltage spikes, but not if I put a load on it, more like only 10V,
this could be purely the fault of the switching controller not regulating properly,
but still would like to know if I got the turns ratio correct.
Also, is a full wave rectifier (centre tap type) of any use in a flyback ? I've never seen a published circuit with one, allways 1/2 wave rectifier (ie one diode)
