Contactless Wireless Charging Station

Description:

The “Contactless Wireless Charging Station” is an innovative working model for students that demonstrates how wireless power transfer technology can be used to charge devices without physical connections. This project simulates a wireless charging station using electromagnetic induction, showcasing a real-world application of modern charging solutions for electric vehicles (EVs), smartphones, and street lighting systems.

The model is built on a 40 × 50 cm Foam Board or Sun Board base, representing a wireless charging hub. The system operates as follows:

• Transmitter Coil (Primary Coil):
  • A 28-gauge copper wire is wound into a coil and connected to a battery clip and IRFZ44N MOSFET to create an alternating magnetic field.
  • This coil acts as the charging pad, transmitting power wirelessly through electromagnetic induction.
• Receiver Coil (Secondary Coil):
  • A 35-gauge copper wire is used to create the receiving coil, which picks up the alternating magnetic field and converts it back into usable electrical energy.
  • The received energy is used to power LED indicators and street lights, demonstrating practical applications in urban infrastructure.
• Circuit Control & Power Regulation:
  • Resistors regulate the power flow, ensuring safe energy transfer.
  • IRFZ44N MOSFET acts as a switch, improving energy efficiency.
  • Battery Clips & Connecting Wires provide stable power to the system.

This project provides hands-on learning in wireless power transfer, electromagnetic induction, and sustainable urban charging solutions, showcasing how contactless charging technology can be used in future energy-efficient systems.
