Voltage ripple in a circuit is found at the output of a transformer after rectifying an AC voltage, by placing a capacitor in parallel. It occurs when there are spontaneous current demands consumed by a circuit, and it has been incorrectly dimensioned in order to suppress them, or when a capacitor has not yet been added, in which case it is a one hundred percent ripple.
The formula is based on the principle of the "capacitor charging formula," adding the frequency term as a divisor of the desired maximum current in order to obtain the current value in a single cycle.
For a full-wave rectifier, multiply the actual frequency value by 2 and enter the result in the frequency field. For a half-wave rectifier, simply enter the actual frequency value.
Fill in three of the four fields to obtain the current, capacitance, frequency, or voltage.
