Step Down to Step Up transformer

Project Description: This project involves constructing a transformer capable of operating in both step-down and step-up modes, allowing students to explore the dual functionality of transformers. The transformer consists of two coils wound around a common iron core. By using switches, the roles of the coils can be reversed, allowing the same transformer to either step down or step up the input voltage.

In step-down mode, the primary coil has more turns, and the secondary coil has fewer turns, resulting in a lower output voltage. In step-up mode, the primary coil has fewer turns, and the secondary coil has more turns, resulting in a higher output voltage.

This project provides an in-depth understanding of how transformers can be used for different applications by simply reversing the connections. It also highlights the versatility of transformers in electrical engineering.

Applications:

• Demonstrating reversible voltage transformation in a single transformer
• Understanding the dual functionality of transformers in electrical circuits
• Educational tool for learning about step-down and step-up voltage processes
• Practical applications in power supplies and voltage regulation systems
