HIgHly resonant WIreless PoWer transfer system overvIeW
Wireless power applications are gaining popularity in many commodity products such as mobile phones chargers. Most of the wireless power solutions have focused on tight coupling with induction coil solutions at operating frequencies around 200 kHz, and Class E, F and S amplifier converter topologies. Recently, however, there has been a push for operation in the restricted and unlicensed lower I...
متن کاملResonant cavity mode enabled wireless power transfer
This letter proposes using the electromagnetic resonant modes of a hollow metallic structure to provide wireless power to small receivers contained anywhere inside. The coupling between a large chamber (used as a cavity resonator) and a small wire loop (used as a receiver) is studied. An analytic expression for the coupling coefficient between the fields in the cavity and a loop receiver is der...
متن کاملAn Overview of Resonant Circuits for Wireless Power Transfer
With ever-increasing concerns for the safety and convenience of the power supply, there is a fast growing interest in wireless power transfer (WPT) for industrial devices, consumer electronics, and electric vehicles (EVs). As the resonant circuit is one of the cores of both the near-field and far-field WPT systems, it is a pressing need for researchers to develop a high-efficiency high-frequenc...
متن کاملWireless Energy Transfer Using Resonant Inductive Coupling
̈C This paper presents a concept of transmission of electrical energy from a power source to an electrical load without physical conducting medium. It is based on the well known principle of resonant inductive coupling and, in particular, resonant evanescent coupling [1] .This well known physics leads trivially to the result of energy efficient midrange wireless energy-exchange. We establish tha...
متن کاملWireless Power Transfer System via Magnetic Resonant Coupling at Fixed Resonance Frequency ―Power Transfer System Based on Impedance Matching
To increase the usage of electric vehicles (EV), a safe and convenient method to charge the vehicles is essential. Recently, an efficient mid range wireless power transfer that uses magnetic resonant coupling, WiTricity, was proposed, and has received much attention due to its practical range and efficiency. Studies show that the resonance frequency of the antennas changes as the gap between th...
