Representative imagery — not this 4TECH build.The problem.
Wireless energy transfer depends on coil geometry, alignment and the electrical load. A useful engineering study must examine the receiving circuit and losses alongside the magnetic coupling.
The engineering approach.
The project connects transmitter and receiver coils with power-conditioning stages to investigate contactless transfer. Receiver rectification and filtering form part of the system, alongside the measurement of electrical behaviour under controlled conditions.
The work considers coil placement, operating conditions and load behaviour as linked design variables. It provides an experimental basis for discussing how a contactless architecture could be scaled and what additional controls and protections would be needed.
The toolkit.
- Inductive coupling
- Coil design
- Rectification
- Filtering
- Electrical measurement
Engineering contribution.
Builds practical understanding of inductive energy transfer and the system requirements behind wireless charging.
Technical scope & validation
The EV-oriented scope is a research application. No vehicle-scale power rating, charging standard compliance or automotive qualification is claimed.
