Here's a very short clip I shot. It shows when I first energize the circuit the neon connected between the drain of one mosfet and circuit ground flashes, also mostly when turned off as well. It appears as though the leg of the neon connected to circuit ground is lighting only. The supply is 12 volts and the circuit is switching to make AC at 90 Hz. http://www.youtube.com/watch?v=CnJE_K5_XSUBeing that I am very new to all this, I have some questions. I hope MileHigh doesn't mind me asking them here, I think it's kinda related to the subject at hand. Q1. How would i accurately describe what I'm seeing there ? Q2. What is the cause of it ? Q3. How do I stop it ? It annoys me. If there is a problem with the setup at times it can cause the neon to flash even during normal operation and that is an indication the mosfets will be heating up quick. Q4. Could it be caused by too much dead time? EDIT: (Causing it to happen during normal operation at certain times I mean.) Oh and Q5. How come it only ever happens with that mosfet and not the other one ? Even if I switch the wires around. Cheers
