Hello dark wizards of firmware Javier here, im trying to use fabulous VESC firmware with 400V IGBTs to drive big motors.
The IGBTs have a minimum switching on-off time of around 2,5us.
So far im having issues with the SPWM modulation not respecting the minimum times resulting in nasty shortcircuits (IGBTs dont have the time to fully open or close).
Im not talking about the general switching carrier signal, im talking about the minimum pulse width the SPWM creates.
Is there any way of limiting the minimum on-off time via firmware??
Thanks in advance
