EMERGING TECHNOLOGIES AND APPLICATIONS OF WIRELESS POWER TRANSFER
Abstract
Wireless power transfer (WPT) has made significant progress in becoming a feasible option for several applications since its first development. The primary objective of this article has been on magnetic resonant coupling (MRC), which is a kind of wireless power transmission (WPT). MRC is particularly noteworthy because of its high transfer efficiency, ranging from 40 to 80%, and its ability to charge many devices from 1 to 50 cm. Magnetic Resonant Coupling (MRC) is an acronym that refers to a phenomenon in which magnetic fields are used to establish a coupling between two or more entities. The usefulness of wireless chargers is the topic of discussion in this article. Although wireless chargers are seen to have slower charging rates than cable chargers, it has been observed that wireless chargers play a part in the preservation of batteries by keeping the charge level within the range of 50 to 80% during the charging process. Notably, Qi 1.2 is a standardized specification that facilitates expedited charging at a maximum power output of 15 watts, specifically operating at 9 volts and 1.67 amps. In the realm of long-range wireless power transfer (WPT), using electromagnetic beams to transmit electricity over considerable distances, spanning hundreds of meters or even kilometers, presents a discernible prospect. The problem of misalignment in wireless power transfer (WPT) and a proposed solution, including using Force Sensitive Resistors (FSRs), are examined. This paper presents empirical evidence showcasing the enhanced efficiency of implementing these solutions. Consequently, it establishes a foundation for wireless power transfer (WPT) in electric vehicles (EVs), drones, and green cells. The use of this instrument greatly facilitates the development of Wireless Power Transfer (WPT) technology and its subsequent advancement.
