Definitions
- the output end of the inverter circuit is connected to the coil device
- the turn spacing D is inversely proportional to the coil loss.
- Mn-Zn ferrite is suitable for medium and high frequency designs
- Ni-Zn ferrite is suitable for high frequency designs.
- the basic requirements for ferrite performance include: (1) higher magnetic permeability and smaller coercive force, which is beneficial to enhance coupling; (2) smaller than loss factor, which is beneficial to reduce signal attenuation; (3) )
- the resistivity is high to reduce the loss of energy efficiency when the sheet heats up; (4) It should have a certain thickness to prevent a large amount of leakage flux from entering the free area.

Abstract
La présente invention concerne le domaine technique de la puissance électrique. Une bobine, un dispositif de transmission de charge sans fil, un dispositif de réception de charge sans fil et un terminal mobile sont divulgués. En vue du problème posé dans l'art antérieur par un faible facteur de qualité de bobine en raison d'un espace et d'une surface limités, la présente invention concerne une bobine, un dispositif de transmission de charge sans fil, un dispositif de réception de charge sans fil et un terminal mobile. Dans la présente solution, compte tenu de la situation selon laquelle le facteur de qualité de la bobine est faible en raison de l'espace et de la surface limités, la conception de structure de bobine est optimisée sur la base du processus original. La fourniture de fils de remplissage à des intervalles entre les fils réduit efficacement au minimum la perte de courant alternatif de l'ensemble de la bobine, réduit l'effet de proximité et l'effet de revêtement et garantit le facteur de qualité de la bobine, ce qui permet d'obtenir un facteur de qualité supérieur avec une certaine surface et un certain volume et d'obtenir une efficacité de charge plus élevée.
