Greetings! This is my first thread. I am creating a 200V bulb dimmer using PWM and IGBT. Currently, this is how I connect the components: The output of the PWM goes into the gate of IGBT. The bulb connects in series with the 220V supply and the collector of IGBT. The emitter of IGBT is put to ground. The problem is, I cannot make the bulb turn on. Please help. Schematic diagrams is of great help.
