Half wave rectifier Circuit with Capacitor in filter

Rectifiers are the circuit which converts AC Voltage to DC voltage. The half wave rectifier is the simplest type of rectifier with a single diode. The output of the rectifier is filtered with a capacitor filter to smoothen.

Forward Bias Diode and Reverse Bias Diode Characteristic Graph
