Wireless Power Transfer for EVs: MATLAB/Simulink Modelling of Coil Coupling

Wireless Power Transfer for EVs: MATLAB/Simulink Modelling of Coil Coupling is most useful as a research topic when the simulation is treated as an experiment rather than a demonstration. The central objective is resonant wireless EV charging with coupled-coil and compensation-network modelling. A strong study fixes the plant and test conditions, defines a baseline, changes one research factor at a time and reports numerical evidence alongside plots.

For doctoral and postgraduate work, the model should make every assumption visible: rated values, data sources, solver settings, controller sampling, initial conditions, boundary conditions and disturbance definitions. This makes the results easier to defend in a thesis, reproduce later and convert into a publication-oriented comparison.

1. Define coil geometry/equivalent inductances and coupling coefficient.
2. Select compensation topology and resonant frequency.
3. Build inverter, resonant network, rectifier and battery/load.
4. Sweep lateral/vertical misalignment or coupling changes.
5. Regulate transferred power or output voltage.
6. Compare efficiency, coil currents and device stress.

Use numerical metrics that map directly to the research objective. Recommended outputs for this topic include:

• DC-to-DC efficiency
• transferred power
• coupling coefficient sensitivity
• coil current
• output ripple
• misalignment tolerance

To turn this topic into a stronger research contribution, start with one baseline and one proposed method, then extend the validation using LCC/LCC comparison, dynamic charging, ferrite/metasurface shielding. The final results section should explain why the proposed method changes the engineering behaviour, not only whether the output curve looks smoother. Include failure cases or operating limits when they reveal the boundary of the method.

• LCC/LCC comparison
• dynamic charging
• ferrite/metasurface shielding
• foreign-object detection
