Each lecture helps me understand better. Thankyou so much :)
dear sir sohail ansari, you deserve respect for all these things, i watch your every video and simply i can say that your lectures are awesome, i am not power electronic engineer and neither i have studied power electronic in my bachelor but because of your lectures i learned a lot and also cleared one of my test for the job of power electronic engineer,,,thamkyou ,,,,keep it up,,,,i have a humble request please share some materials regarding application of power electronic in motor drive,,,,love from across the border..
You are first I think who giving full fledged content regarding power electronics even reputed Gate coaching institute's
satya narayana yes you are right..rest of them are just trying to give lec not full concept
Power electronic's best teacher.
Not even made easy teacher given such a clear concept by taking money.
But you have provided us at free of cost.
Thanks a lot sir..
Respected Ansari Sir,
This was indeed the best lecture of whole series !!
Kudos to entire GATEMATIC Team !!
Great Job !!!
Most welcome...share jarure krna.
Really unbelievable sir koi itna asaani se PWM ko kaise bta sakta... really every single person here is applauding for your contribution is even less for your teaching technique and knowledge. GOD BLESS YOU SIR.
and the answer is 77.15 degrees.
Most welcome...share this with ur frnds..all the best
Thank you sir
Sahi kaha sir Apne...we are gatematic and genique students now we will not have any kind of doubt in dealing with harmonics...bus khelengey uske Sath😄😄😄😄😄hats off sir🙏🙏🙏🙏🙏
sir aap kamaal ho. main made easy main padha hoon (2015 e batch ), wanha pe sir ne kaha tha ki ye question(gate 2014 wala) inappropriate hai, data missing hai, bahoot khushi ho rahi hai aapka video dekh kar.main pakka donate karoonga . aur job lagne pe to aur bhi donate karoonga . thank you so much. lagta hai abb india main coaching ki jaroorat nahi padegi.
Words cannot explain my happiness sir....
Thank you so much for ur effort...
Jindagi me ek chance ayega apko milne ka....
Inthajaar kar raha hu us din keliye ...
Guruji😍
77.15°, short trick to find fourier series is awesome sir. Hats off to u
Yar ye home work question was unable to solve before watching these lecture now i solve easly .so proud of u sir . god bless u .
most welcome..all the best for gate.
Baap Matlab baap
No one has teach this things like you have
And you don not have skip any single thing
Thank you for this mind blowing lectures
In my semester days when I used to study power electronics, mujhe lagta tha ki ye duniya ka sabse tough subject hai... But ab to lagta hai ki M.Tech kar lu power electronics se.... Sir u are awesome... Salute you aap jaise teacher mil jaye to kuch bhi muskil nhi hai🙏🙏🙏🙏🙏🙏🙏🙏😀😀
Outstanding teaching sir..I alwaya gratitude you..you made me, pwm tech such so easy...after watching ur classes
Alpha=77.1546
After watching ur lectures, it's easy to solve gate questions Sir... Thank you so much
sahi baat sir, being a GATEMATIC student ab Fourier and PWM ka fear khatm. Thank u very much sir
Sir your way of explaining concepts is totally unique... Awesome it is
77.154 degree
Thanku so much sir pichli baar iska lamba integration karne ke dar se solve Ni ki thi
Ab ho gya na..enjoy kro.. 😊
Sir aap mahan ho, love and respect to u all a lot
ans is 77.15
Maza aa gya sir apse pdhke.
I hitted like bcoz i am a GATEMATIC student.
thanks alot . U made PE an easy subject.
Amazing concepts ;)
Best teacher for power electronics
sir ur effort is going to best way
Shortcut was amazing, may Allah bestow upon u, the choicest mercy. Thanks sir.
Proud to be a GATEMATIC student.
Thank you sir..
Thanks sir for short cut it made homework too easy to calculate.
I can say only one thing for my Guru... Arjun got Krishna , I got You ❤️
If you could kindly suggest books for topics like SPWM SELECTIVE HARMONIC ELIMINATION
77.15
Sir your teaching techniques are realy miraculous
Plz explain how to come divide by √2
@@pithimanon3142 bro that is for converting to max we know Vrms=Vm/√2
can you provide the solution
really amazing sir,thank u somuch for ur best way of teaching
77.146 degrees sir....
You made it so simple... thank you sir
Sir, pls discuss about PMOSFET, PBJT, IGBT, and protection of thyristor
ALPHA = 77.1549
SIR YOUR LECTURE IS AMAZING BECAUSE LAST TIME I SOLVE THIS QUESTION 1ST TIME IN HALF HOUR BUT TODAY WITHIN 25 TO 30 SEC
77.17 deg..
Really learned a new thing.. thank you sir
Most welcome..share this video with ur frnds/juniors so that they can also get benefit from this lecture...all the best..
I can not understood per unit concept and how 3rd order are eliminated
Sir tq for your great effort and may i know any differences between she pwm and svpwm...thanks in advance sir...
Sir, how to eliminate all the lower order harmonics 3 5 7th simultaneously, because we are discussing removal of any1 harmonic at a time eg 3th or 5th. How practically the removal of all lower order harmonics is done???
Sandipan Paul watch todays lecture..ur query will get resolved..i will upload in evening...
ok sir..thank you
Awesome one of the best lecture
Really nice video sir. thanks ☺️☺️☺️
dear sir,
In stepped output waveform like 5 level, 9 level etc, how can we calculate the fourier series as well as the switching angles.
77.15° ... thanks for your great help towards us...
You said, it is pole voltage, which is equal to 0.5Vdc. So, while writing bn, it will be 4Vdc/n*Pi (...), Because Vab=Vdc, not 0.5Vdc 2:57
Thanku sir....you are awesome
U are just awesome
thanks
77.154° sir.... Thankyou so much sir
I UNDERSTOOD ALL CONCEPTS
Alfa = 77.14° , thank you sir for this wonderful lecture
77.15°
Shortcut is really helpful sir.....
Thank you very much sir...
Thanks a lot for the wonderful lectures.
The answer is 77.15 degree.
can you show me the solution
thank u so much sir
Jabardast shortcuts tha
sir , When the Signal and system course will be updated , i'm waiting for it for the preparation
Pawan Singh i am waiting for machine...bcz esa lag rha he machine bhi fad dege PE ki tarah kyuki technical ...hw
Thank u very much sir..!👍👍👍👍👍👌
77.154 . Thanks a lot. God bless you
77.146 degree..
thankyou sir for the shortcut..
Ans - 77.15
Given Vdc is 100v, b1rms = 50v
Bn formula from case 1 and divide by √2 and equate it to 50 you will get the answer. This might help those who are confused.
77.154. THANKS FOR MAKING SUCH WONDEFUL SUOET CUT FOR US
(4*100/√2π)(1-2cosα)=50 => α=77.15°
Good...mazaa aa rha hai na?
Sir apka explain karneka tarike me pata nehi kaun sa jadu h ki 1 bar video dkhte hi sab samaj me ajata h! _/|\_
:) Dusra bar dkhne ka need e nehi hota h! Hats off to you sir for making power electronics so easy.
Bas share krte rho..taaki baaki ko bhi aasan lage...all the best
Sure sir :)
Why In this question we r considering output voltage as line voltage not pole voltage of inverter??
If nothing is mentioned ,
Then what we have to consider??
Thankyou sir
77.15 degree ,awesome video sir
i like your lectures, thank you Sir
Sir aap itna fastly knowledge dete ho ki hum kuch capture nhi kr pte
after this lecture it was very easy to solve, alpha=77.15
Great..enjoying or not?
Obviously enjoying😃😃
77.17 good lec...earlier i am doing whole intrigation bet 0 to 360
Good good..upgrade urself now...sinusoidal PWM is coming soon..
GATEMATIC Education yeh sir yeh PWM meshe ane ka chancehena 2019 me 1que to?
Vijay Prajapati yes..bcoz 2018 me eknbhi question nahi puchha hai
Thank you Sir !
Thank you sir ji
Most welcome...mazaa aa rha hai na?
