I am having issues driving big motors with VESC firmware and IGBT (they explode when driven above 90% duty)
is that spike normal for trapezoidal modulation?
In the oszi capture the motor is running at low speed and no load, yes i am respecting the deadtime specs for this IGBT 2,4us
Yellow: Phase-Ground Voltage
Blue: high side Gate signal
Pink: low side Gate signal
Green: 0.5mA shunt detecting shortcircuits
