What a great job explaining this subject. However I like to point out a small mistake. At 6:52 min, the table and graph do not match.At step 1, Vbo is -1/2 so (+1/2 - (-1/2) = Vs. Step 2, Vbo is 0 so =1/2 -0 = 1/2 Vs. No big deal but it might confuse people who try to follow the sequence. 2 thumbs up to you Sir and thanks for posting.
Apologies for the errors and thank you for pointing them out :)
No big deal⚠️
Udo thats a horrible mistake i had spend 30mins to figure it out 😐
We follow this. That's no matter.
The graphic explanation step by step is excellent! Thank you!
Great job buddy you have covered all the concepts in the easiest possible way really appreciate your work and efforts.
this is a really great video. the explanation, the animation, everything about this video is awesome.
Just looking at these videos, I can see the hardwork you put in them.
Great content,good explanation.
Keep up the good work☺
Thank you so much for appreciation! Means a lot :)
Very concise and clear explanation! Thank you!
Great tutorial!! Very systematically and nicely explained.. Hope you plan to continue..
Thank You so much, glad you liked it.. Do subscribe to stay updated :)
ty for the video bud keep up the good work happy new year!!!
i deeply appreciate your explanation.. a dedicating one.. Thank u.. keep it up and forward..
Explanation is simply superb.... very very helpful...
make more videos related to electrical engineering and power electronics.. Ur explanation is superb and it's literally helpful ☺
Thank u so much...I felt very easy to understand..✌
This was wonderful thank you.
Your way of explanation is superrrr sir plz provide some more on power electronics
Merci bcp ,très bn explication simple et suffisante pour bien comprendre le principe de conversion (dc-ac)
Thank you so much, nicely explained.
Thank you so much, it was very helpful n simple in understanding...
Nice work.It was really helpful
good explanation, easy to catch-up
Best best best 💯💯💯💯 thank you for saving me from KT🙏🙏🙏 more power to u bro🔥💯
you saved my day :)
it is very helpful, thank you very much
Tq soo much sir good explanation and easy to understand
Nice work...
Keep going.
Very helpful video Sir. Plz make some on chopper circuit also.It will be very helpful. Thank you
Excellent explaination
Bro super bro. Thank you very much.
may god bless u. very useful :D
Easy to understand....👌
Great job😍
it waas too helpfull for me to understand
thank you very much
very good video!
Thank You!
Good explanation
Great stuff
Many thanks
awesome bro thanks
Very nyz notes thank u
thank you ❤
Helpful Thank you
LOVE YOU BROOOOOOOOOO
brilliant
Thanks, super !!!
thank you it's helpful
Glad u liked it :)
Good job
good work
Thank you so much anurag mittal :)
Tq sir

Make a video on it's formulas about harmonics and all
Thankyou sir and I also want PWM concept
+Aravindhan Gandhi welcome! Will try to cover it soon :)

Can we expect some more videos on power electronics sir?
Thanks god
if we give 600 dc volt from solver panel to vfd how many maximum ac volts can be acheved by vfd as a out put volt
is there a video for PWM explanation ? I mean sinus modulation
How does the Commutation happens in 3p SCR Inverter driving Motor? Expecting reply ASAP
Can you please make a video of 120 & 180 mode with Delta connection
Can you please explain the working and switching sequence of 6 phase inverter?
sir can u pls make a video on single pulse and sin pulse pvm inverter
Sir,Why we are using 120 degree mode instead if 180 degree mode?
What are the disadvantages of 180 degree mode?
Thank you. You truly helped me.
Now, why would I use a 120 mode instead of 180 mode?
I am talking in terms of losses and all the geek stuff.
In 180 degree, as one switch turns off(after 180 deg), next has to turn on(for 180 deg) immediately without a lag in time(180+180=360). That can cause a short circuit and damage the system . In comparison 120 degree offers safer commutation.
For answers related to losses and other parameters refer to this answer on quora:

I appreciate the gesture :)
Which software it is?

Dear sir
What is the value of IGBT using this type switching 3phase inverter circuit , to ON for Vge=4v~5v and its output is Vce=250v &above and Ic=Ie=3A &Above and its switching time below 10ns.
or
what is the value of thairistor 3phase 220v 3A inverter ckt ?
Thank you.
Bhai Vbo and Vco ki waveform gtl hai
Great!! Great!! Great!!!
Can u give me your intro I mean who u are and what is your profession etc etc..
Thank You so much!
Nice video dude, u have talent for be Russian 👌😅
any video on 3 phase ac-dc power converters????
Not yet, but will cover the domain in near future. Do Subscribe for updated content.

better than my fucking teacher.....
In 7:33 , check Vb0 plot
Current graph ??
What is the angle between 2 current wave form?

Very nice video Can you do this in Marathi ?
Glad u liked it. Not familiar with the engineering terms in Marathi yet 😅.
at 4:46 time. the Switch 5 5 needs to be open. Great explaination
Thank You!
Fourier expansions not explained
Thank u so much...I felt very easy to understand..✌
