Wireless Power Transfer (WPT) has become an innovative and practical solution to overcome the drawbacks of conventional wired charging techniques. Unlike traditional methods that rely on physical connectors, WPT delivers electrical energy through electromagnetic induction or resonant coupling between a transmitting coil and a receiving coil integrated within the portable device. This technology provides significant advantages in terms of user convenience, safety, and flexibility, as it eliminates cable wear and tear, minimizes electrical hazards, and supports charging without direct physical contact. The proposed design focuses on optimizing coil geometry, resonance frequency, and alignment to maximize power transfer efficiency while reducing energy losses. Additionally, the integration of advanced power electronic circuits ensures stable voltage regulation and improved system reliability, making the charging process faster and safer. The system is particularly suitable for smartphones, tablets, and other portable gadgets, where mobility and compactness are essential. With further advancements, WPT has the potential to extend beyond consumer electronics into applications such as electric vehicles, biomedical implants, and industrial automation, thereby transforming the way electrical power is delivered and utilized.
