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
Please look in the Motor Control SDK MCSDK for implementation of Space Vector and other libraries.
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?
