I wonder how far the similarities go between FOC control and SVPWM modulation and from which point on wards they are different from each other?

edit:

Can anyone point out a very basic primer from where I can learn about SVPWM?

    The concepts are orthogonal. FOC can be implemented with SVPWM. – Eugene Sh. Feb 07 '19 at 18:13

    Orthogonal... great word! – JRaef Feb 07 '19 at 19:02
  • A better question would be SVPWM and SPWM –  Feb 07 '19 at 19:22
  • @JonRB The OP already asked that question, and other related questions: https://electronics.stackexchange.com/questions/420281/spwm-vs-6-step-pwm-vs-svmpwm – Elliot Alderson Feb 07 '19 at 20:13
  • ok good, I guess he is just conflating terms. Looking at that question you just posted –  Feb 07 '19 at 20:32
  • can anyone point out a very basic ab-anitio introduction to SVPWM.. i am struggling to learn it but most papers i got so far go over and above my head.. and they have so many other things discussed in them that its difficult to make sense of exactly what is SVPWM. – scico111 Feb 07 '19 at 22:23

Here is an excellent write-up I found on SVPWM.

From that site:

"Space Vector Pulse Width Modulation (SV-PWM) is a modulation scheme used to apply a given voltage vector to a three-phased electric motor (permanent magnet or induction machine).

The goal is to use a steady state DC-voltage and by the means of six switches (e.g. transistors) emulate a three-phased sinusoidal waveform where the frequency and amplitude is adjustable. ..."

An excellent animated vector diagram is provided on the above page. Unfortunately, the URL is too long for SE EE, and SE EE does not allow use of URL shorteners. A working link can be found in the comments below or by reconstituting https:// bit.ly/svpwmcontrol.

  • @RussellMcMahon thank you for the edit. I will be more mindful of this in future posts. – bptsj Dec 02 '20 at 15:31
