Actually you shouldn't count 6 in triplen. Triplen harmonics are only supposed to be odd multiples of 3 so 6 is already out since even harmonics are absent due to odd symmetry.
Sir ek suggestion h video improvement k liye... Ek bigger pointer ya highlighted pointer ho toh better lagega...pata chalta h where pointer is moving and kahan point kar raha h... This seems insignificant at normal speed but to save time I watch at 1.5x speed and Usme pointer gumm ho jaata h... :-)
You have made one mistake while finding the Fourier series of phase voltage. You have put b1 instead of bn in final expression of Van. I have checked some other books also. Please let me know if I am correct or wrong.

cos(nπ/3) =0.5 for n=6K+-1...so that's why sir took value of b1 @ 6:52...just in case somebody didn't get it
b1=2Vdc/pi and bn= 8Vdc/3n*pi
please like if i m correct
😇
thank u sir for making our concept strong . You the the best teacher in the world
Fantastic lecture guruji🙏🙏
sir in PMW single pulse why did you omit the term sin(nPi/2) as if we put 3 it becomes -1 ?
Actually you shouldn't count 6 in triplen. Triplen harmonics are only supposed to be odd multiples of 3 so 6 is already out since even harmonics are absent due to odd symmetry.
yes you are absolutely correct. thank you
Sir make a video on design of snubber circuit and parallel , series operation of scr .......other devices of thyristor family
Thanks again for your effort
At 11:15 3n harmonics ar absent as because sin(n*pi/3)=0 for n=3,9,15........so in line voltage it should also be n=6k+-1
Single pwm trick was just great...thank you sir
please, can you tell me which video he describes the Fourier expression for single PWM?
7.01min.... Sir u put the value of b1, instate of bn in Fourier series expression Van .. Why?
Sorry I got it.....thank you sir from my bottom of 💓......
thank you sir. vanikam
I did celebrate the new year with this video. Sad new year for me, happy is for u

u r awesome sir
hmm thik bol60
thanks a lot sir
😇😇😇superb
Sir ek suggestion h video improvement k liye... Ek bigger pointer ya highlighted pointer ho toh better lagega...pata chalta h where pointer is moving and kahan point kar raha h... This seems insignificant at normal speed but to save time I watch at 1.5x speed and Usme pointer gumm ho jaata h... :-)
Ye mai koshish kiya tha pointer bada krne ka..but option nahi hai isliye nahi kr rha hu..dusra platform pr dekhunga..agar hua to kr denge..ok
Thank you sir... SIr, have you any trick to find fourier series of Triangular waveform ??
thank u sir
Most welcome..
Sir..for phase voltage Fourier expression on putting n=6, Bn is not equal to zero as cos(2π)=1.. please clear it sir
All even harmonics are already eliminated....only 3, 9,15,..triplen are extra which are also eliminated by cos2pi*n=-1
3n harmonics are eliminated n=1,3,5,7..
nice video
What will be the fourier series expression for line voltage in delta connected load in 180 mode
Sir please upload video on pwm techniques
Its already uploaded..check out the playlist
GATEMATIC Education thnx a lot air
At 5:36 b6 is not 0,as cos(2Π) is not -1
Even harmonics won't be present at all since it is a wave with odd symmetry.
5:22 sir how b6 could be zero??? cos(2pi)=1 , not -1
yes , you are right
Upload the videos on power system and other subjects also
How the line voltage waveform is not a odd waveform clearly explain please
@4:37 why the n can't be even number ? 2,4,6,8 , if n=2 the express is (1+cos2pi/3) ,it's not equal to 0 , can you explain it .
It is half wave symmetric so it is not having even harmonics...🤓
Sir plz try to complete PE by the end of August...plzz sir
It will be completed...dont worry

have u gone through full lecture...check out again...its corrected in the lecture only..ok
3.14 min ..pi/3 to pi/2 you have written 2vdc/3 ..I think it is wrong plz correct it sir
Sir synchronous machine ka lecture kab suru hoga...
b6 was not zero at 5:29
How can the b6 be zero? 😕😕👀
Even harmonic is already 0
@@soumalyadeogharia6161 sorry I have no idea RN because it's been one month since my semester ended and I am done with this stupid course
Sir b6 will not be equal to zero
Plz correct it sir
Please help...
Thank u sir
