what is ripple factor of any waveform
ripple factor is specified for waveforms containing ac and dc components... if Vrms= RMS value of ac component Vdc=DC value then Ripple factor= Vrms/Vdc
Actually, Ripple Factor = I'rms/Idc = V'rms/Vdc , where I'rms and V'rms are ripples . theoritically \[i = Imsin(wt) ; 0\le wt \le \pi\] \[i = 0 ; \pi \le wt \le2\pi\] \[I'rms = (1/2\pi) ( \int\limits_{0}^{2\pi} i^2 d(wt) ) ^{1/2}\] \[Idc = (1/2\pi) \int\limits_{0}^{2\pi} i d (wt)\] by solving \[I'rms / I dc\] we get the ripple factor like this Ripple factor of any wave form => r = \[\sqrt{(Irms/Idc)^2-1}\] thats all :)
