Dear student,
The simple capacitor filter is the most basic type of power supply filter. The application of the simple capacitor filter is very limited.A capacitor (C1) is connected across the output of the rectifier in parallel with the load.the capacitor must charge up fast with preferably no discharge at all. Better filtering also results when the frequency is high; therefore, the full-wave rectifier output is easier to filter than the half-wave rectifier because of its higher frequency.
