I've been working on a Single Phase IGBT Inverter with PWM and Zero Crossing Detector for months. Turns out I forgot to build the gate driver (i know it's stupid but I'm also working and studying at the same time so it's kinda hard to catch up) However,
my zero crossing detector is used as PWM from Arduino. (i only use digitalread and digitalwrite code with pin 3 as input and pin 9 as output)
At first, I connect pin 9 straight to the high side IGBT gate and inverted pin 9 to the low side IGBT gate. It was a mistake because the gate needs 15V to be turned on and the IGBT overheated because of shoot through.
Now I need a chip that takes logic 2,75 V input and amplifies the voltage without interfering the frequency. Is there any?
Here's the schematic to the circuit.
Sorry for bad English. I'm running out of time and sanity.
