Full-Wave Bridge Rectifier Filter + Regulator DC Power supply

Click For Summary
SUMMARY

The discussion focuses on calculating parameters for a Full-Wave Bridge Rectifier Filter and Regulator DC Power Supply. Key calculations include the secondary peak voltage (V secondary peak = V2 / 0.707), ripple voltage (VC1 P-P = IDC / (2f * C)), and the voltage drop across the load resistor (VRL p-p). The user specifically seeks assistance in determining the DC voltage across the capacitor (Vc1-dc), the Zener current (IZ), and the ripple voltage across the load resistor (VRL p-p).

PREREQUISITES
  • Understanding of Full-Wave Bridge Rectifier circuits
  • Familiarity with Zener diode voltage regulation
  • Basic knowledge of capacitor filtering techniques
  • Proficiency in AC to DC conversion calculations
NEXT STEPS
  • Calculate Vc1-dc using the formula Vc1-dc = V2P - (2 * Vd), where Vd is the forward voltage drop of the diodes.
  • Determine Zener current (IZ) using IZ = IDC - Iload, where IDC is the average load current.
  • Analyze ripple voltage across the load resistor (VRL p-p) using VRL p-p = (IZ * RL) / C.
  • Explore the impact of filter capacitor values on ripple voltage in DC power supplies.
USEFUL FOR

Electrical engineering students, hobbyists designing power supplies, and professionals working with rectifier circuits and voltage regulation techniques.

Ok, there are a few calculations on this problem that I am having difficulty with. This is a past homework assignment which is why the answers are filled in. They are all correct.

Anyways I approached the problem in this manner:

V secondary peak = V2/ .707

The voltage drop across RL is ZZT

IRL= ZZT/RL

VC1P= V2P - Both forward biased diode drops.

VC1 P-P (Ripple) = IDC / (2f * C)

VRS= Vc1 dc - Vzt

IRS= VRS /RS


The three that I am having trouble with are: Vc1-dc , IZ, and VRL p-p (Ripple)

Can anyone help me out?

Thanks.
