Design and Parameter Optimization of Double-Mosquito Combination Coils for Enhanced Anti-Misalignment Capability in Inductive Wireless Power Transfer Systems

Wencong Huang,

et al.

Abstract: This paper proposes a novel double-mosquito combination (DMC) coil for inductive wireless power transfer (IPT) systems to improve their anti-misalignment capability. The DMC coil consists of a mosquito coil with single-turn spacing and a tightly wound close-wound coil. By superimposing the magnetic fields generated by both coils, a relatively uniform magnetic field distribution is achieved on the receiving coil plane. This approach addresses the challenges of significant output voltage fluctuations and reduced… Show more

“…Specifically, an optimization study was performed on the application of the coil material to the high-temperature superconducting coil [1]. Research on omni-directional receivers was developed to reduce power transmission loss due to misalignment in wireless power transmission [2,3]. A study was undertaken to reduce the change in output due to the misalignment of electronic devices and electric vehicles using relay coils [4,5].…”

“…Wireless energy transfer systems rely on close magnetic coupling between coils to efficiently transmit energy. When the relative positions of the coils change, the effectiveness of the magnetic coupling is significantly reduced, resulting in decreased energy transmission efficiency [9,10]. Additionally, coil misalignment may cause the magnetic field to concentrate in areas where it should not, increasing the temperature of local tissues, potentially leading to thermal injury or other biological effects, and thus increasing the risk associated with use.…”
