Line Output Transformer

Former Member

Hello I think this isn't the right place to put this but here it goes;

 

I am making a circuit using a 555 timer, a IRF830, voltage regulator and lopt, hence giving out a spark. the lopt is from an old t.v.. I know the most basic thing, which is the thickly insulated wire from the LOPT to the anode terminal (covered by a rubber cap). i wanted more info on this transformer. Especially where, what and how the other two wires do.

    Sounds like what you really need to do is find the pins for the other half of the seconday coil and the primary coil, for what you are trying to use it for, you can ignore the rest.



    Finding the pin for the the secondary coil requires a power supply, and a DMM, finding the primary coil is relativlely easy as it's very low impadance, so you just measure the resistance between each pin until you find a pair with about 1 ohm between them.



    I did a bit of googling to save me typing a long reply, if you look go look at http://leoricksimon.blogspot.com/2007/05/flyback-driver.html you'll find all you need.


    P.S. I think the full pinout varies from manufacturer to manufacturer, so if you really need to know what all the pins do, you'll need to look for info on the specific part you have.
