Rectifier Filter alternate Dc or Vr P-P calculation.

SUMMARY

The discussion focuses on calculating the peak-to-peak (P-P) ripple voltage for a full-wave center-tapped rectifier filter. The user initially struggles with the equations for ripple voltage and DC voltage, specifically using I / (f * C) for ripple voltage and VDC = VOUT P – (VR P-P /2) for DC voltage. They seek alternative formulas to derive ripple voltage without prior knowledge of DC voltage. The relevant formula for half-wave rectifiers is provided as 1 / (F * R * C) * Vin-p, which can be adapted for full-wave applications.

PREREQUISITES
  • Understanding of rectifier circuits, specifically half-wave and full-wave configurations.
  • Knowledge of electrical components such as capacitors (C) and resistors (R).
  • Familiarity with voltage concepts, including peak voltage (Vin-p) and ripple voltage (VR P-P).
  • Basic grasp of electrical formulas related to filtering and voltage calculations.
NEXT STEPS
  • Research the formula for ripple voltage in full-wave rectifier circuits.
  • Learn about the impact of load resistance on ripple voltage in rectifier filters.
  • Explore the role of capacitor selection in minimizing ripple voltage.
  • Study the differences between half-wave and full-wave rectification in practical applications.

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.

Thanks.

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.

Thanks
