Ripple Frequency Calculator


Calculating the ripple frequency in electronic circuits is crucial for designing and analyzing various power supplies, especially in switching power converters. The ripple frequency determines the stability and performance of these circuits. Utilizing a ripple frequency calculator simplifies this process, providing accurate results swiftly.

How to Use

To utilize the ripple frequency calculator effectively, follow these steps:

  1. Input the values of capacitance (C), load resistance (RL​), and peak-to-peak ripple voltage (Vpp​).
  2. Click on the “Calculate” button to obtain the ripple frequency (f).


The formula for calculating ripple frequency in a capacitor-input filter circuit is as follows:


  • f = Ripple frequency (Hz)
  • IL​ = Load current (A)
  • C = Capacitance (F)
  • Vpp​ = Peak-to-peak ripple voltage (V)

Example Solve

Consider a scenario where:

  • Load current (IL​) = 2 A
  • Capacitance (C) = 1000 µF
  • Peak-to-peak ripple voltage (Vpp​) = 5 V

Substituting these values into the formula, we get:


Q: What is the significance of ripple frequency in electronic circuits?
