Research Problem
Wireless Power Transfer (WPT) technology has become increasingly important in
applications such as electric vehicle charging, consumer electronics, biomedical
implants, industrial automation, and Internet of Things (IoT) devices. Most modern WPT
systems rely on resonant magnetic coupling to transfer electrical energy without
physical connectors. This technology offers greater convenience, improved safety, and
reduced maintenance compared to conventional wired charging systems.
Although considerable progress has been made in improving wireless power transfer
efficiency, a major challenge remains. Most existing systems are designed assuming
perfect alignment between the transmitting and receiving coils. In practical applications,
however, perfect alignment is rarely achieved. Even small horizontal or angular
misalignments can significantly reduce magnetic coupling, leading to decreased power
transfer efficiency, increased energy losses, overheating, and reduced charging
performance.
