Static Wireless Charging using Inductive Power Transfer

This project demonstrates static inductive wireless charging in MATLAB/Simulink using mutual inductance between coils for contactless power

This MATLAB/Simulink project models a Static Wireless Charging System based on Inductive Wireless Power Transfer (WPT) using mutual inductance. The system uses magnetic coupling between a primary (transmitter) coil and a secondary (receiver) coil to transfer electrical energy wirelessly across an air gap.

The transmitter coil is excited by an AC source, creating a time-varying magnetic field. This induces a voltage in the receiver coil proportional to the mutual inductance (M) and rate of change of current in the primary winding.

Key Features:

• Implementation of inductive WPT using a mutual inductor model in Simulink

• Demonstrates wireless energy transfer through magnetic coupling

• Analyzes voltage and current waveforms at both transmitter and receiver

• Shows the relationship between coupling coefficient (k), mutual inductance (M), and output power

• Suitable for static wireless charging research and demonstration

How to Run:

1. Open the .slx model in MATLAB/Simulink.

2. Adjust coil parameters such as inductance and mutual coupling if required.

3. Run the simulation.

4. Observe the induced voltage and current on the receiver side.

Applications:

• Wireless charging pads

• Electric vehicle charging (contactless)

• Medical or sealed devices where wired charging is not possible

• Power transfer in isolated/rotating systems (industrial use)
