Wireless power transfer technology for shore-to-ship applications
| Resumo: | The continuous growth of maritime transportation has driven the demand for more sustainable and efficient solutions for supplying energy to ships while docked at port. Conventional shore-to-ship power systems rely on heavy cable connections that are complex to handle, prone towear, and require frequent maintenance. Thiswork presents the development and implementation of a wireless power transfer (WPT) system for shore-to-ship applications, with the goal of increasing safety, flexibility, and reliability in port electrification. The proposed system integrates a power electronic converter composed of a three-level neutral point clamped (3LNPC) rectifier, a three-level inverter connected to the wired interface, and a high-frequency H-bridge inverter associated with the inductive power transfer (IPT) link. The design focuses on scalability, efficiency, and galvanic isolation between the shore grid and the ship, ensuring compliance with maritime safety standards. Communication between the control platform and the power stage is achieved through optical fiber, providing robust, low-latency signal transmission immune to electromagnetic interference. Experimental validation was carried out on a laboratory-scale prototype, demonstrating both the wired connection and wireless power transfer. The results confirm the feasibility of applying IPT technology in maritime environments, paving the way for cleaner, safer, and more convenient shore connection systems. |
