Hello everyone. I am developing a 3kw solar inverter circuit. I just want to know if I can drive a single IGBT using unipolar supply (say just +15V). Current flowing through my circuit is between 15-17A and operating frequency is 20 kHz.
It's a general practice to add a negative supply(-5V to -8V) to facilitate speedy IGBT turn-off. I want to know whether it would be safe to skip this additional voltage requirement and replace it by passive methods like additional resistor(small value) arrangement for IGBT turnoff.
If there's any other method for safe igbt turnoff without involving additional voltage supply please let me know.

Best regards and thanks in advance.
