TMS320F28069M: Short pulse suppression

Part Number: TMS320F28069M


Hello,

I would like to implement short pulse suppression within Instaspin since any pulse lower than a couple hundred nanoseconds won't even turn on the IGBTs we are using and from the EMI point of view they are the most noisy ones.

I have found this post:

in which the best way of doing it seems to be modifying HAL_writePwmData in the following way:

value_sat = (uint16_t)_IQsat(value, period, _IQ(minimum_value);

However the question related to how this would affect overmodulation (since I am using it) and how to work around it remains unanswered.

Regards,

Javier
