    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

    sir in PMW single pulse why did you omit the term sin(nPi/2) as if we put 3 it becomes -1 ?

  • @UditOjha
    @UditOjha 5 лет назад +5

    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.

  • @techspecialinformation7746
    @techspecialinformation7746 5 лет назад +1

    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

    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... :-)

    • @GATEMATICEducation
      @GATEMATICEducation  6 лет назад +2

      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

    Sir..for phase voltage Fourier expression on putting n=6, Bn is not equal to zero as cos(2π)=1.. please clear it sir

    • @KarishmaticZenYog
      @KarishmaticZenYog 6 лет назад +6

      All even harmonics are already eliminated....only 3, 9,15,..triplen are extra which are also eliminated by cos2pi*n=-1

    • @syedali102
      @syedali102 5 лет назад

      3n harmonics are eliminated n=1,3,5,7..

    At 5:36 b6 is not 0,as cos(2Π) is not -1

    • @UditOjha
      @UditOjha 5 лет назад +2

      Even harmonics won't be present at all since it is a wave with odd symmetry.

  • @techspecialinformation7746

    5:22 sir how b6 could be zero??? cos(2pi)=1 , not -1

  • @linkonbrowse
    @linkonbrowse 4 года назад

    @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 .

    • @Noone-rd4hz
      @Noone-rd4hz 4 года назад

      It is half wave symmetric so it is not having even harmonics...🤓

  • @kumarvishal8291
    @kumarvishal8291 6 лет назад

    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.
