TMS320F28379D: Phase angle between two ePWM

Ashwini Kumar Dubey

Part Number: TMS320F28379D

Is it possible to generate phase angle difference between ePWM2A and ePWM2B? For example ePWM2B is 45degree phase shifted w.r.t. ePWM2A?

    Hi Ashwini,

    The Phase Shift functionality in EPWMs means that the TBCTR is loaded with the TBPHS value when a sync pulse occurs. Since channels A and B share a counter within a single EPWM module (e.g. the EPWM2 module), you cannot have phase shift between two channels A and B. However, there are other ways where you can simulate a phase shift such as using the deadband module to implement rising and falling edge delays, or using different action qualifiers and CMPx values as well. Let me know if these methods would be able to work for you or if you have other related questions here.

    Best Regards,

    Allison
