TMS320F280049C: Is it possible to apply instaspin when a snubber is applied to the FET?

Part Number: TMS320F280049C

Dear Expert,

Can I drive a motor using instaspin when a snubber is applied to the FET? If there are any precautions, please let me know.

Sincerely,

No. The snubber will impact the motor parameters.

Dear Yanming Luo,

Although it seems like there are many things to consider, wouldn't it be possible to use it if we give top priority to points where the waveform distortion due to the snubber is relatively low when selecting current and voltage sampling points? Such as dead-time, start of PWM period, top point of counter and so on.

Sincerely,

Eu-Heon

It could be very complex. We didn't have any research on this. It's difficult to provide any suggestions to you. You may try to search if there is any research on some of engineering websites since any of the other motor control algorithms have the same challenges.
