EXPERIMENT 05

Title of the experiment: Design and simulate a circuit to convert AC signal to DC using full wave rectifier (center tap transformer) with and without capacitor filter and extract the circuit parameters. 

Aim or objective: 1. To explain the working of full wave rectifier and study its behavior with and without filter.

 2. To calculate and compare ripple factor for a full wave rectifier with and without capacitor filter 

List of equipment required to conduct the experiment with their specifications:

Circuit Diagram: 

a. Full wave rectifier without capacitor filter 

b. Half wave rectifier with capacitor filter: 

RESULTS:

1. FWR Without Filter:

The RMS voltage () is .

The DC voltage () is .

The ripple factor () is , indicating significant ripple content in the output.

2. FWR With Filter:

The RMS ripple voltage () is .

The DC voltage () increases to , showing a smoother and more stable output.

The ripple factor () is , indicating a much smaller ripple compared to the unfiltered output.

Conclusion of the experiment: 

1. Adding a filter to the Full Wave Rectifier (FWR) significantly improves the quality of the output voltage.

The DC voltage () is higher with the filter due to reduced ripple.

The ripple factor () decreases dramatically with the filter, confirming the effectiveness of the filtering process.

2. The filter reduces the AC components in the rectified output, resulting in a smoother DC voltage suitable for powering sensitive electronic devices.

3. This experiment demonstrates the importance of filtering in rectifier circuits to achieve a cleaner and more stable DC output.
