Matlab should be a Bachelor's engineer degree. It is captivating and the explanation was excellent. Thanks for always giving us, junior engineers, the ingredients and the recipe to help us to make the greatest cake so that the Senior engineers can be jealous.
Can you ans one doubt? pls 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?

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.
She intends to show you that the pink is comprised of the two red ON one at a time and soetes both off. Her animation could be clearer if she shows the duty cycle of the red vectors by their lengths, not by flashing them in time.
Can I ask, what is the effect of chosen PWM frequency on torque output driving PMSM using SVM? Do you get less torque accuracy and more torque ripple at higher speeds if you use a lower PWM frequency?
Yes, at lower PWM frequencies you can expect more torque ripple. Field oriented control coupled with high PWM frequencies is an effective way to obtain accurate torque response. This discovery page provides more information www.mathworks.com/discovery/field-oriented-control.html
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.
If the motor were not moving, you just apply a stationay vector (not rotating = 0hz) that applies an equal and opposite force against the outside force that would otherwise tend to move the rotor. Move to the -Q axis (or change 180deg or just change the sign of the command) to apply force in the opposite direction. All the while, you need to track the motor's position to stay in sync with its axis (d,q) if it moves.
This is pure gold. Clear, well structured and straight to the point. Great great job!
Two semesters in college was not enough to explain that matter that clearly, thank you for this video, Pure gold!!
the animations are great and they help 1000 times for my imaginative dense brain
Glad it was helpful!
One of the best SVPWM video I have visited! Good Job..
Thank you!
The greatest explanation ever
Good job! It helps me to understand the inductive flyback by animation.

Thank you for the feedback, much appreciated!
Wonderful explanation.....Simple and very easy to understand.
What a nice class! Congrats!!!
Thank you very much for very clear and educative videos.

congratulations! excellent content.
Thank you! Useful information and very well explained.

Excellent efforts, thank you..!
I did not understand if the red means switch is off then how in the on time duration calculation it is actually the opposite?
She intends to show you that the pink is comprised of the two red ON one at a time and soetes both off. Her animation could be clearer if she shows the duty cycle of the red vectors by their lengths, not by flashing them in time.
yes, it looks like red should mean that the switch is on. Probably a little mistake?

Can u please make tutorial series on sensorless bldc control?
Great woman
Thank you very much
Nice explanation.Can anybody tell what animation software is used here for creating vector movement?
Maybe java
Useful information
Good.
Really great content

The 3rd in the V_LN cancels in the V-LL.
Very good madom
How do one get internship at Mathworks ?
Have a strong cv , then apply
well appreciated
Great job!!!
Could/would you use this kind of modulation to hold the motor on a specific angle?
If the motor were not moving, you just apply a stationay vector (not rotating = 0hz) that applies an equal and opposite force against the outside force that would otherwise tend to move the rotor. Move to the -Q axis (or change 180deg or just change the sign of the command) to apply force in the opposite direction. All the while, you need to track the motor's position to stay in sync with its axis (d,q) if it moves.
Speed Control of Induction Motor using Fuzzy PI Controller Based on
Space Vector Pulse Width Modulation applications please
great,keep going on
ablam cok iyisin🧠
Nice explanation
Wonderful information
Plz make more vedioes on ev topology
Very nice ..!!
Madam can you please explain changing of rotation by space vector modulation
You just change the sign of the Q command so the commanded vector position changes 180 deg.
