Give the waveform of +15, -7V at points 6, 7, 4 and 5 on the IGBT to see how much dead zone there is

I can't tell what the dead zone setting is.

Dead time generally refers to the use of two-phase or three-phase PWM to control IGBT. If there is no dead time between the two, it is easy to make the upper and lower tubes turn on at the same time.
