Rectifier Filter alternate Dc or Vr P-P calculation.

  1. Jul 3, 2009 #1
    I have a predicament. I'm trying figure out the P-P ripple voltage of a Half-Wave rectifier filter, but the only equation I have is: I / (f * C) yet to find the current I need the DC voltage which I don't have yet. The same goes for the DC voltage. I have the equation: VDC = VOUT P – (VR P-P /2) yet I do not have the ripple voltage yet. So my question is, are there any alternate equations that will allow me to find the ripple voltage without the DC voltage, or the DC voltage without the ripple voltage.

    Forget the first post. Now all I need is a formula to calculate Vr P-P in a full wave center tapped rectifier filter. If it is of any help the formula for the half-wave is: 1/ (F*R*C) * Vin-p.
