The AC ripples can be reduced in a rectifier circuit by using capacitive filter by _______ the capacitance value and by _______ the input frequency.

Rectifier

• Rectifiers are electronic devices or circuits that convert alternating current (AC) into direct current (DC).
• Based on the output waveforms, the rectifier is classified into the following:
   

1.) Half wave rectifier

2.) Full wave rectifier

The AC ripples in a rectifier circuit can be reduced by using a capacitive filter by increasing the capacitance value and increasing the input frequency.

1. Increasing the capacitance: A larger capacitance allows the capacitor to store more charge, which helps in smoothing out the voltage by providing a more stable DC output with fewer ripples.
2. Increasing the input frequency: Higher frequency means the capacitor has to discharge over shorter intervals between peaks, which results in lower ripple amplitude.
