I am controlling transistors from a PWM generator. Duty cycle is %25. I checked for dead time. It is safe. Now, here I used safety bulb in series with the main (220VAC). When I plug it in Lamp goes fully on after 1-2 second later it goes almost off (just a little bit blinking). I thought first light is because capacitors are charging. So my questions are;
After I start pwm generator, I can see arcs but bulb also goes almost fully on. Is this a sign of a failure or short in the circut ?
I am checking voltage across C3 after I start pwm. Depending on my distance adjustment on flyback's secondary cables to have arc, it shows up to 1800V.
I will later add voltage feedback and current feedback. Other then these additions, what kind of improvements should I do? Or is this a completely ridiculous way?
