A Full Wave Bridge Rectifier is a common electrical device used to convert alternating current (AC) into direct current (DC). It’s a popular choice for science projects, especially for high school students in Class 12, as it provides a practical example of electrical engineering principles. Here’s a description of a Full Wave Bridge Rectifier science project working model suitable for Class 12 students:
- Objective: The objective of this science project is to design and build a Full Wave Bridge Rectifier circuit, explaining its working principles, and demonstrating its ability to convert AC voltage into DC voltage effectively.
- Working Principle: A Full Wave Bridge Rectifier is a circuit that rectifies both halves of the AC voltage cycle. It uses four diodes arranged in a bridge configuration to achieve this. As a result, the output voltage is a pulsating DC signal, which can be smoothed using a capacitor for a more constant DC voltage.
- Circuit Diagram: Create a clear and labeled circuit diagram of the Full Wave Bridge Rectifier setup. Include all components and connections.
- Assembly: Assemble the circuit on a breadboard or PCB following the circuit diagram. Connect the transformer to the AC supply and then to the bridge rectifier circuit. Connect a capacitor in parallel with the output to filter the rectified voltage.
