The attachment has a picture file that show the transformer specification.
it said tie( pin 3 + pin 4 + pin 7) to get 7200 Volt AC.

1) Does that mean that I connect pin 3 to pin 4 and then connect pin4 to pin 7 ?
2) Next. Pin 12 and Pin 13 will automatically give an output voltage of 7200 Volt .
Is this correct ?
3) I am trying to use this transformer with a DC battery of 9 volt along with a MOSFET
to increase the voltage from 9 volt to 7200 volt. Can it be done based
on the specification sheet ?

That was the insulation test condition, not an output voltage.

Hi Chris65536. Thanks you for the answer.
1) Is this correct that this transformer is not a step up transformer ?
2) Is this correct that this transformer can only output 24 Volt at a maximum of 0.35 amp
as stated in the specification sheet ?
3) the primary has 3 parts. With pin 3 and pin 1 with an input voltage of 125 to 375 Volt
With pin 4 and Pin 6 with an input of 12 volt and 0.10 amp.
With pin 7 and Pin 8 with an input of 12 volt and 0.70 amp.
How do you use these 3 primary to get an out put of 24 volt and 0.35 amp ?

This transformer is designed for switching power supplies, but I'm not sure how it's supposed to be wired. Also, the datasheet for this part at Digikey shows a different arrangement of the coils. What are you trying to do with it?

 

I am trying to use this transformer with a DC battery of 9 volt along with a MOSFET
to increase the voltage from 9 volt to 7200 volt or some high voltage value like 5000 volt.

Do you have a web address for the datasheet of this transformer at Digikey?

A DC power source will produce no output with that transformer. Or any transformer! Transformers only work in AC.

 

It is true that a DC power source will not work with a transformer alone, but with a MOSFET
it will work, because a MOSFET will switch on and off quickly and therefore current flow through
it.

 

That is correct, but you didn’t state what the MOSFET was used for. How are you using the MOSFET to generate AC? I got what you said; what I am asking is how you are turning the MOSFET on and off to create AC?
