FULL-WAVE RECTIFIER
AIM:-
To find the Ripple factor and regulation of a Full-wave Rectifier with and without filter.
APPARATUS:-
Bread Board
Transformer (6-0-6v).
P-n Diodes, (lN4007) ---2 No’s
Multimeters –2No’s
Filter Capacitor (100μF/25v) -
Connecting Wires
Load resistor, 1KΩ
PROCEDURE:
1. Connections are made as per the circuit diagram.
3. Connect the ac mains to the primary side of the transformer and the secondary side to the rectifier.
4. Measure the ac voltage at the input side of the rectifier.
4.
5. Measure both ac and dc voltages at the output side the rectifier.
6. Find the theoretical value of the dc voltage by using the formula Vdc=2Vm/П
7. Connect the filter capacitor across the load resistor and measure the values of Vac and Vdc at the output.
8. The theoretical values of Ripple factors with and without capacitor are calculated.
9. From the values of Vac and Vdc practical values of Ripple factors are calculated. The practical values are compared with theoretical values.
RESULT:-
The ripple factor of the Full-wave rectifier (with filter and without filter) is calculated.
