Can anyone tell me what type of inverter the attached schematic is? I've run across this similar design several times while working on el wire drivers, and I have not been able to find the same circuit on Google. This just takes a 12 volt input and steps it up to ~140VAC. I wish to understand the operation f this circuit better. The transformer's primary winding is 1.36mH, the feedback winding is 21uH and the secondary is 238mH. C2 is a 0805 SMT chip, so the capacitance is unknown. Just guessing by the thickness, I would hazard to say it is less than 0.05mf.
