Alternating Reversing Sequencing Space Vector PWM in DMC Library?

Hi Adam,

The Alternating Reverse Sequencing is different than the DPWM technique.  The Alternating Reverse Sequencing has the following pattern over one PWM cycle:

V0, Va, Vb, V7, V7, Vb, Va, V0

The DPWM technique has the following pattern:

V0, Va, Vb, V0, V0, Vb, Va, V0

In other words, whenever you have a time slot dedicated to a null vector, chose V0.  This results in one phase's bottom transitor remaining on for 120 degrees of the motor fundamental voltage waveform.  For the next 120 degrees it switches to a different phase's bottom transistor turning on, and the third phase's bottom transistor being on for the final 120 degrees.

Regards,

Dave

Thank you for the response Mr. Wilson.  It's great to hear from you!  I am a huge fan of your work!

Thanks Adam for your kind and affirming response.  Best wishes for success on your motor control project.  :-)
