Inductance Calculation

[Bakr]

I want to design a flyback transformer which can output 50watts. I want to operate it at 10 KHz. My Input is 15Vdc and required O/p is 8kVdc.
Does any body help me how can I calculate the required primary inductance.
And also turn ratio.

i like to help you on this one bakr but ive never designed a flyback transformer before and i use mainly the ones with the biult in hv trippler, but you can allso use transformers in reverse mode to , power, from your flyback driver circuit it dose ok , the turns ratio for the flybacks are different i think to the transformers , so so if the inductances are simliar you may find a few ideas around that rarether than to try biulding one,

The primary inductance is not all that important but you can calculate it. I can't remember what the formula is, but it has to do with the transformers specifications. Incidentally, the transformer can be operated in the specified frequency range which has to do with it's inductance.

Hi Bakr,

You can

[Kevin Weddle]

Just one second Ante. I believe DC describes current that flows in one direction. So can see that a transformer can in fact work with DC.

Perhaps pulsed DC. You need current change in an inductor so that the varying flux (magnetic flux) can cut across to the other inductor (mutual inductance).
