Nobody in India can teach like u even in costly coaching centers also.
Thanku so much sir we are really blessed to have u as our teacher
Most welcome..share jarur krna.
True
You are right mam
sir , I'm watching your P.E videos from lec-01 till now and sir it is sure that no one can cover this subject in the way you did. In terms of content and simplicity as well. I have seen notes of this subject from reknowed institute of gate coaching but they are just watse and nothing. your content is really worthy to be watched . First time I can say that some teacher made a subject really really easy which looks really tough .so Hatsoff to you sir. thank you sir
Thank you so much sir...
1) 4 pulses
2) 13.5 deg
.2355 rad
"MPWM" was one of those rare topics, I preferred to leave whenever I saw it in the journey of my 2018 GATE preparation and also during my college days. I used to think that may be this concept is too much tough and the college teachers also prefers to skip this topic. But now I am realising the root of this skipping tendency. It was the way of representation in Bhimbra, for which I have skipped it. They made it so long, that it looks horrible. That's why I used to memorise only single PWM. But in this lecture, when you said that first you will cover MPWM then Single PWM, I understood the approach. Probably you will put N=1 in the expression of MPWM to get the results of Single PWM. And after watching this much lecture, I am not gonna do the same mistake which I have done in 2018. So a big thanks to you sir. Hope one day I will get a chance to meet with you face to face even if my GATE 2019 would go wrong. And I promise you, if one day I will succeed in life, I will surely help GATEMATIC in any possible way according to my ability. :)
By the way N=4
w=0.235 rad.
Gatematic will always welcomes u...first settle in ur life...have a decent job then we can meet..all the best
Sir May God bless you. We all need teacher like you. Thank you so much.
Sir, thanking you immensely for providing us these best lectures.
Answer to the numerical in the end of lecture is:
1) No. of pulses in positive half cycle = 4
2) Width of each pulse = 13.5° or 0.075π radian or 0.2355(in radian).
Sir you r awesome i found power electronics very tough before watching your videos but alhamdullillah now i am loving power electronics thanks a lot Suhail sir ☺️☺️
Thank you so much sir..u are the real teacher..i was a student of ace academy ...i didnt understand power electronics inspite of attending lectures there...ur videos are superb..
1) N=4
2) w= 13,5 ( degree) . 0.235 in rad.
Thank u sir
Excellent
Understood. I tried to understand many times but today I got cleared
Thank you sir - நன்றி அய்யா
thankyou sir for giving us these best lectures...no one is teaching like you sir...
1) 4
2) 13.5 degree or 0.075 Pi radian
Excellent lecture. Understood each & every point easily. Thank you sir.
Thank you so much sir.. It means a lot for so many students that you are providing these quality lectures in such precise manner. It helps a lot. I get and understand each and every point you tech. God bless you!! 😊
Thanks for sharing this videos....(from Argentina)
well explained sir, even we cant learn it in coaching centre, please upload more lectures on machines,, bhagwan aapko hamesha khush rakhe
Speechless !!!!!
Salute 👌
Amazing....No words in dictionary ....To wish...Thank you so much
You are the best Power electronics teacher in India I guess
1. 4
2. 0.2356 rad
Thanks a lot for the wonderful lectures.
at 23:00,how the time period of traingular wave is considered........it is considered differently from that of square wave
Just loved it!! Cant wait for upcoming lectures.. upload it soon sir.... cant believe i m able to do gate questions so easily..
its already uploaded
thank you sir!! giving us a good knowledge of power electronics
Aesthetic lecture. Simple and Excellent explanation. Very nice.
so glad i found you. great
Thank you Sir.
N=4
W=0.2356 radians
Explanation way 👌👌👌👌👌👌❤️❤️..thank you sir
Very nicely explained, nothing can be better than this
i understood each and every concept and now i m very happy thanku sir
sir I must say you are an amazing teacher and an extraordinary talent 🫡🫡🫡
Thank you sir, I got all the answers correct
Thank u so much sir my all doubts are clear after see ur lecture
Sir very good morning and tgank u soo much for explaining the concepts so well.. and a humble request Sir.. can u teach how to write 8085 assembly level program to design :
When a coin is inserted and when it is valid, port 1 gives code FFH. If it's valid, check whether the request is for tea or coffee at Port 2. 04H code at Port 2 is the request for tea and 40H code at Port 2 is the request for coffee. Open the value for liquid to come out with 04H code for tea and 40H code for coffee at Port 3. These codes at Port 3 are to be used for value operation. When port 4 gives code 00H, value is to be closed with code FFH. Repeat process can start with a new coin. If coin is invalid, 00 indication at Port 5 is to be given and the instruction for inserting a new coin can be given.
Upsc 2010 mains question sir
Thank you so much for understanding to PWM, And I solve your numerical the answer is N=4,W=0.23561
n=4, w=0.23 ....................................................thanku so much sir..............may god bless you
excellent teaching sir..mind blowing
Most welcome..share jarur krna channel ko..
Thank you sir
Number of pulses =4
Width of each pulse = 13.5 in deg
Thank u from d bottom of heart again and again Sir .....All good will fr u Sir
most welcome..share this video with ur frnds/juniors so that they can also get benefit from this lecture..
Thank you Sir.
N=4 & W=13.5deg.
Thanks for your lecture sir, I have a doubt at @19:31 sir, whether it has to be -Vc
1) Nos. of Pulse = 04
2) Width of Each Pulse = 0.2356 radian
If switching frequency is changed then the waveform of Vo(t) will change.if waveform of Vo(t) changes then Fourier series of Vo(t) will change. If F.S of Vo(t) changes then Vo1( max) will change.But at 4:43 u are saying that although switching frequency of inverter changes we can't change Vo1(max).
Plzz... explain this sir....
Very good lecture sir.
sir, u r great this really help me a lot.
Thank you sir for your kind effort 😊😊😊😊😊
Waiting for next lecture
already uploaded
No of pulse 4
And pulse width is 125msec
Seriously... Awesome sir...
thank u sir...
Thank you Sir,
Synchronohs machines kab tak we can expect?
cannot say..let me complete power electronics first..life is highly non linear..so cannot say about tomorrow..
Awasome lecture sir , I am engineer and working in. Power electronics company can you make lecture pdm switching technique please
Thank You Very Much Sir. Lots of Love and Respect
Yes No Coaching Center Is teaching the PWM in Detail
thank you very much sir
its very clear
most underratted lecture
I don't understand why useful information like this get few likes . Anyway thank you Sir for this information.
THANK U SO MUCH SIR. N=4 and W=0.235 radians
1. No. of pulses (N) = 4
2. Pulse width of each pulse,(w) = (3*pi/40) radians, 13.50 degrees, and 1.5 mSec.
Milisecond wala answer sahi h na sir?
Thank you.
no its 13.5*20/360 = 0.75msec
What is this milliseconds?
sir can you explain why single bridge is not called as multilevel inverter even though it is possible to generate three level output by providing different gate pulse
Nice Explanation
Sir, in PWM . 1) on what basis the pulse depend on multiple PWM ..in half cycle ,?
2) on what basis the frequency domain and time domain depends on in square waves ?
🙂
N=4,W= 0.2355 radian or 13.47 degree
Thank you so much sir🙏🙏
Sir n=4, 13.5 degree
Very good explanation sir
correct
This is very useful sir..
Sir if the voltage is produced in pulse form... Then the voltage is not continuous... At that time how the load will behave when voltage is zero in between the pulse.
No words for u sir 😇
Xcellent sir
nice explanation sir
N=4
W=13.5 degree
Hi sir,
Number of pulse in Half cycle (N)=4
Width of Pulse(W)=0.235 in radian
width of pulse (W)= 13.5 in degree
Thank you.
correct
Thanks for video sirji
N=4 AND W=13.5 IN DEGREE OR 0.2355 IN RAD.....THANK U SIR
Correct...most welcome..
Nice...👌
.... I need to buy PWM for hydrogen production. Hydrogen unit need 220volt 2500watt.
N=4 and width of each pulse is 6.75.
Thank u so much sir
N =4
W=0.2356 radian OR 13.5 degree
correct
Homework : number of pulse in half cycle = 40
Width of each pulse = 3pi/400
Thank you sir
great lecture
👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌Lecture sir
i Understood after my B.TECH 2013
now in 2018 i Got 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏😅😅
N=4 pulse width=13.5 degree
Thanks sir... Most waited video
most welcome
Bhai Maza aa gya
Thnx sir
Thankuuu soooooo much sir...... Thankuuuuuuu
Thanks, in the lecture you mention that W=pi/N(1-m), actually when m=1 the width of the pulse should be maximum but for your derivation at m=1 , the PW will be equal to zero at m=1
m=1 implies Vcmax = Vr
=> No where Vcmax > Vr
=> No PWM wave..
=> Hence 0 pulse width
4,13.5 degrees
Sir, what is the meaning of 2d?? Why it has taken multiple of 2 ...... please explain sir....
N=4
W=0.2356 rad
Thank you sir.....
correct
Thank you
hello dear prof Ansari... the classification says the pwm is applicable to single phase..and 3 phase means the only possibility is 120 or 180 mode..!! but i feel this classification could be made bit clear!!
he taught everything in the next lessons
Sir,in case of m pwm N=3 here it will be always be 3?
Sir can u provide a similar typ of lecture in signal and system
How I can increase the power of high frequency pwm inverter. parallel in D.C Side or in A.C Side.
Thank you sir
Just a thought on comparison..it should be mod(Vc)>mod(Vr) right?
right
4
.236 radian
Thank u sir
Good evening,sir ji
Why width is taken as 2d? Why not d or 3d etc
no of pulse =4
width (3pie/40)
👌👌
nice video
1.4
2.(.235 in radian)
1) 4
2) 13.5 degree
