Understanding Space Vector Modulation| Brushless Motor Control with Simulink, Part 5

Space vector modulation (SVM), also known as space vector pulse width modulation (SVPWM), is a common technique in field-oriented control for induction and permanent magnet synchronous motors (PMSM). SVM generates the pulse width modulated signals to control the switches of a three-phase inverter, which then generates the three-phase voltages required to drive the motor at a desired speed or torque. In this video, you’ll learn how SVM can generate a voltage vector at any given angle and magnitude by alternating between basic and null vectors. The video also compares space vector modulation to sinusoidal PWM (SPWM) which is another commonly used method for motor control.

This is pure gold. Clear, well structured and straight to the point. Great great job!

[Ykotb]

Two semesters in college was not enough to explain that matter that clearly, thank you for this video, Pure gold!!

[abhishekkhunte]

One of the best SVPWM video I have visited! Good Job..

[qiangli]

Good job! It helps me to understand the inductive flyback by animation.

[kidslearningbymadhankarthi]

Wonderful and very easy to understand.

[viktorbeldjajev]

Thank you very much for very clear and educative videos.

[adricat]

Thank you! Useful information and very well explained.

It probably would be helpful if you show how the resultant vector is comprised of adjacent vectors that vary in magnitude as the resultant vector sweeps through a sector, such that scaled vector can be added head to tail.

in customized SVPWM, the PWM Generater takes "Vabc and Vdc" as input and we attach SVPWM after Inverse Park Transform block which gives "Valpha and Vbeta" as output so how and what to attach to SVPWM then?

[narendra]

Can u please make tutorial series on sensorless bldc control?

[superman-slqb]

Nice explanation.Can anybody tell what animation software is used here for creating vector movement?

[vijayyadlapalli]

Speed Control of Induction Motor using Fuzzy PI Controller Based on
Space Vector Pulse Width Modulation applications please

[milanthedrummer]

I did not understand if the red means switch is off then how in the on time duration calculation it is actually the opposite?

[omidnaderi]

please give us information about harmonic content of SVM generated voltages. because I saw that I have considerable amount of third harmonic in my output voltage.

[arvinderbali]

How do one get internship at Mathworks ?

[vaughnmonkey]

Could/would you use this kind of modulation to hold the motor on a specific angle?

[balaraju]

Madam can you please explain changing of rotation by space vector modulation
