This tool calculates the ripple voltage (peak-to-peak) for a full-wave bridge rectifier.

Input the Load Current, Frequency and Capacitor value (select the units using the drop down menu).

**Formula**

**V _{Ripple}**

**= I**

_{LOAD}/(f*C)where,

**V**is the peak-to-peak voltage ripple_{Ripple}**I**is the load current_{LOAD}**f**is the frequency**C**is the capacitor is used to smooth the output voltage to a specified ripple.

**Example Calculation**

For a load current of 1 Amp, 50 kHz frequency, Capacitor value of 100 uF, the ripple voltage is 0.2 Volt. Increasing the capacitor size by a factor of ten to 1 mF reduces the ripple voltage to 20 mV.

The peak-to-peak voltage can be converted to RMS voltage (approximating it as a sine wave).
