OK GUYS!!
i got a schematic that i need a very good electronics guy to look at. Its
for a gas turbine. ignitor system high voltage, around 2Kv. can someone help
me decipher a few things on it????It will only take a minute....... Thanks
Bill

    I can take a shot at it.

    Hi Bill,

    I have worked with turbines, their ignitors and fuel control systems
    before, attached is a photo of a turbine on a test stand under stamp
    control.

    So what's to decipher?

    Well thanks Ron,

    Thanks for responding. I have some schematics for an ignitor system but
    there are some questions I have that the designer wont answer. I dont know
    why but he wont so I figured I'd ask someone else and see if anyone can tell
    me what I need to know. Im not the best when it comes down to electrical
    knowledge, but that is why they call it a hobby. You learn. If you have
    schematics on your ignitor system I would be more that thankful to see them.
    I will down load the schematics I have, take a look and let me know what you
    think.

    This is the message from the email I got with the schematics.......

    Attached is a flyback circuit I have used to generate 2kV and store it on a
    capacitor. The auto ignition coil is used to create a spark in the normal
    way across a SMALL gap, e.g. a spark plug. (Do not attempt to try to bridge
    more than 1mm or so, as the isolating diodes D3-D7 will fail.) D8 is the
    same as the other diodes.

    The small spark shorts out the storage capacitor, and it then dumps its
    energy into the gap, producing the big spark shown on my web page.

    U2 is a low voltage spark gap ~300V, the sort used as transient suppressors
    in telecom systems. It discharges C8 into the coil primary to give the small
    trigger spark.

    Thanks again Ron,
    Bill

    so, what are the questions?
    it looks like a pretty straight forward commercial circuit.
    osc, pwm driver chip, high power driver to first transformer, spark drive to
    second transformer.

    Hi Bill,

    What's the question regarding the circuit?

    Ron

    Ron,

    Thanks for looking at the schematics...... Bill
