Customer ServiceThe designing of this circuit can be done with a capacitor (C) as well as load resistor (RL). The rectifier’s exciting voltage is given across the terminals of a capacitor. Whenever the voltage of the rectifier enhances then the capacitor will be charged as well as supplies the current to the load.
Adding a large capacitor to a rectifier is necessary to store and transfer energy so that a smooth, ideally non-varying voltage results. As noted previously, under heavy load the ripple would increase in amplitude and the average voltage would drop.
Whenever the voltage of the rectifier enhances then the capacitor will be charged as well as supplies the current to the load. At the last part of the quarter phase, the capacitor will be charged to the highest rectifier voltage value that is denoted with Vm, and then the voltage of the rectifier starts to reduce.
A half-wave rectifier with a capacitor-input filter is shown in Below Figure. The filter is simply a capacitor connected from the rectifier output to ground. RL represents the equivalent resistance of a load. We will use the half-wave rectifier to illustrate the basic principle and then expand the concept to full-wave rectification.
Throughout the negative half cycle, the flow of current in the second diode gets the filter to charge the capacitor. But, the capacitor charging occurs simply while the applied AC voltage is superior to the voltage of the capacitor. The capacitor in the circuit is not charged fully, so the charging of this does not occur instantly.
Throughout the conduction time, the capacitor gets charged to the highest value of the voltage supply. As the voltage among the two plates of the capacitor is equivalent to the voltage supply, then it is said to be completely charged.
