DESIGN AND CONSTRUCTION OF A WIRELESS POWER TRANSFER SYSTEM

This study explores the design and construction of a Wireless Power Transfer (WPT) system, focusing on its potential applications in various fields, including consumer electronics, electric vehicles, and medical devices. The objective is to develop an efficient, reliable, and safe WPT system that minimizes energy loss during transmission. The proposed system employs resonant inductive coupling, which utilizes magnetic fields to transfer power between two coils—one transmitter and one receiver. Key components of the design include the selection of appropriate coil materials, optimization of coil geometry, and the implementation of a feedback control mechanism to enhance efficiency. The project involves constructing a prototype, followed by extensive testing to evaluate performance metrics such as transmission efficiency, range, and load capability. Results indicate that the system achieves a significant improvement in power transfer efficiency compared to traditional wired methods. Furthermore, the study discusses the implications of WPT technology on future energy solutions, addressing challenges such as alignment, safety, and standardization. The findings contribute to the growing body of knowledge in the field of wireless energy transfer, highlighting its transformative potential in promoting convenience and sustainability in energy usage.
