Later, using Multisims software, this coil design is produced in simulation. The suggested coil design's power efficiency is examined and contrasted between computed and simulated results. Finally, based on the results of the power efficiency, a definitive discussion is presented....
A new methodology for ensuring that a three-coil wireless power transfer system is more energy efficient than a two-coil counterpart is presented in this paper. The theoretical proof and the conditions for meeting the objective are derived and practically verified in a practical prototype. The key...
A novel analytical model of inductively coupled wireless power transfer is presented. For the first time, the effects of coil misalignment and geometry are addressed in a single mathematical expression. In the applications envisaged, such as radio frequency identification (RFID) and biomedical implants...
The conventional structures of the coil and the metamaterial are used in the system, so the universality of this method is further illustrated. This paper is organized as follows. The theoretical analysis of the frequency reconfigurable wireless power transfer system is illustrated in “Theoretical ...
A Three-Coil Wireless Power Transfer System using Self-Resonant Open-Bifilar Coils A common trend in the field of wireless power transfer consists in the use of more than two coils in order to extend the link distance in terms of efficien... CMD Miranda,SF Pichorim - AEUE - International...
In the inductive contactless battery charging, the power transfer capability and efficiency are mainly depending on the coupling coefficient (k) between the inductively coupled coils. In this work, the spiral and square coil configurations were experimentally made from litz wire as well as another spi...
Wireless power transfer is a nonradiative type of transmission that is performed in the near-field region. In this region, the electromagnetic fields that are produced by both the transmitting and receiving coils are evanescent fields, which should not t
This paper presents a novel resonance-based multicoil array structure to wirelessly charge or power up apparatus, like smart phones, computer mouses, smart animal research systems, or implanted medical devices. The proposed array consists of a novel multicoil inductive link, whose primary resonator ...
The model has two 3D microstrip(PCB with substrate) coil. One for transmitter and the other is for receiver. My model has two physics: 1) Magnetic and electric Fields 2) Electrical Circuit Electrical circuit supplies Sin power to transmitter in 4MHz frequency. The receiver coil is connected ...
A novel foreign-metal detection-system for wireless power transfer (WPT) is described. Foreign metal was heated only when placed between the primary coil and the secondary coil. By having the metal in that position, the quality factor of the secondary coil (Q2) decreased rather than other para...
