 Experiment Name:

Design, Construction, and Testing of a Full-Wave Rectifier using AutoCAD.


Theory

A full-wave rectifier is an electronic device that converts an alternating current (AC) input into a direct current (DC) output. Unlike a half-wave rectifier, which uses only one half of the AC waveform, a full-wave rectifier utilizes both halves, thereby increasing the efficiency of the rectification process.

A full-wave rectifier typically consists of a transformer, four diodes arranged in a bridge configuration, and a load resistor. The transformer adjusts the input AC voltage to the desired level. The diodes then rectify the AC signal, allowing current to pass through only during specific portions of the AC cycle, effectively flipping the negative halves of the waveform to positive. The result is a pulsating DC voltage that is further smoothed by a capacitor filter to reduce ripples.


Apparatus:

Transformer (Step-down, Center-tapped)

Four diodes (1N4007)

Load resistor (1 kΩ)

Capacitor (100 µF)

Breadboard

Connecting wires

Oscilloscope

Multimeter


Circuit Diagram:



Procedure:

Design the Circuit:

Use AutoCAD to design the schematic of the full-wave rectifier, ensuring the correct placement of the diodes in a bridge configuration and the connection of the transformer and load resistor.

Construct the Circuit:

Assemble the circuit on a breadboard based on the AutoCAD schematic.

Connect the transformer's primary winding to the AC supply and the secondary winding to the bridge rectifier circuit.

Testing:

Connect the oscilloscope across the load resistor to observe the output waveform.

Use a multimeter to measure the DC output voltage and current.

Record the observed waveforms and measured values.



Discussion

The experiment demonstrates the design, construction, and testing of a full-wave rectifier. The AutoCAD schematic ensured precise placement and connection of all components, facilitating the construction on the breadboard.
