Dear TI team,
We are going to do a new control card for 3- phase application, for that we need some reference code for this MCU: TMS320F28379D
1) SPACE VECTOR PWM (SPWM)
2) SINE TRIANGLE PWM
Best regards,
Rushabh Shah
Dear Nima Eskandari,
I had checked in motor control SDM, but I didn't find any document related SPACE VECTOR PWM & sine triangle pwm, can you give some link or path, please.
I'm not an expert on this but isnt the SVGEN the space vector generator?
In the MCSDK?
