Characterization Of Resonant Coupled Inductor in A Wireless Power Transfer System
Keywords:Wireless Power Transfer, Coupled Magnetic Resonance, Resonance Frequency, Inductive Coupling.
A novel technology known as wireless power transfer based on coupled magnetic resonances allows for the transfer of energy in the non-radiative near-field using coupled magnetic resonances. In this study, a single-loop inductor that serves as the system's receiver and transmitter is designed, simulated, manufactured, and experimentally characterized. To make analyzing the transfer characteristics of a magnetically coupled resonator system easier, a circuit model is proposed. This structure relates the output voltage in the receiving loop to various transfer orientations and distances. Simulated and examined at a predetermined driving frequency. About 580 kHz is the system's driving resonant frequency. According to experimental findings, energy can still be transmitted under most circumstances even when the recipient is shielded. Walls, books, wooden items, organic glass panels, leather, and textiles are examples of non-metallic objects that have no effect on the flow of electrical energy. Energy transfer demonstrates that the square of the difference between (1/r2) the transmitting and receiving resonance loops has an inverse relationship with the transfer efficiency. The transfer power and efficiency decrease as the distance between them increases. The near-field idea is portrayed in this.
