DESIGN AND IMPLEMENTATION OF A LOWCOST WIRELESS POWER TRANSFER SYSTEM

Wireless power transfer (WPT) is a promising technology that allows the transfer of electrical energy from a power source to a device without any physical contact. It has various applications in areas such as consumer electronics, biomedical implants, electric vehicles, and industrial automation. However, the cost of implementing WPT systems has been a significant challenge, especially in developing countries. This paper presents the design and implementation of a low-cost wireless power transfer system. Thispaper presented the design and implementation of a low-cost wireless power transfer system based on magnetic resonant coupling. The system achieved an efficiency of 73% with a power transfer of 3.67W to the load. The proposed system has several advantages over traditional wired systems, and its low cost makes it suitable for widespread adoption. Further research can be done to optimize the system's design and improve its efficiency.
