Hi all,

Can anyone please tell me how are the test cases outcomes for the specification " The Space vector modulation concept has to use DC link voltage to determine Pulse Width Modulation Output".

Thanks in advance

Hi,

Can you please elaborate your query. Are you referring to AN93637 and related projects.

Hi,

Thanks Jobin, and i have further small questions:

Do we get only Sine wave form output if we go with FOC motor control?

And can you please send me a screenshot of output waveform in FOC? And also PWM for all sectors in SVM algorithm? so that i get a clear idea of all seperate forms.

thanks

Hello,

Ideally it should be a perfect sine-wave. You can find the phase current waveform from AN93637 Figure 18.

Waveform changes based on the quality of motor - check Appendix E.

Thanks
