    • A system, method and apparatus for contact-less charging of battery operated devices is presented. There is a host charger with a power converter and resonant tank circuit and a portable device where the battery is located, with a battery charging control IC. The method obviates the need for a voltage controller in each of both the host and the portable stages, thus decreasing complexity and increasing efficiency. The charging of the battery in the portable device is controlled by a charging controller therein, which is in continual electric communication with the host, whose output power the control IC dynamically monitors and controls. Two embodiments for the charging circuitry in the portable device are presented. In one embodiment component count is minimized but battery charging is not optimized when the battery voltage is very low. In the other embodiment charging efficiency is maximized regardless of the output voltage of the battery, but additional components are utilized.
    • 提出了一种用于电池供电装置的无接触充电的系统,方法和装置。 有一个主机充电器,带有电源转换器和谐振回路以及电池所在的便携式设备,带有电池充电控制IC。 该方法避免了在主机和便携式级中的每一个中的电压控制器的需要,从而降低复杂性并提高效率。 便携式设备中的电池的充电由其中的充电控制器控制,该充电控制器与主机持续电通信,其控制IC的动力监视和控制的输出功率。 介绍了便携式设备中充电电路的两个实施例。 在一个实施例中,当电池电压非常低时,元件数量被最小化,但电池充电未被优化。 在另一实施例中,无论电池的输出电压如何,充电效率最大化,但是使用附加组件。

    • A wireless charger charges a storage battery of a portable electronic device in a wireless manner (non-contacting or contact-less) so that a variation of charging efficiency is not serious though the storage battery is placed any position of the wireless charger. The wireless charger is provided with a primary coil for generating a magnetic field so as to charge a subject, which is provided with a secondary coil, by means of inductive coupling with the secondary coil. The primary coil includes an outer coil arranged with a predetermined winding number and a predetermined size; and at least one inner coil arranged to be included inside the outer coil. The outer coil and the inner coil are arranged so that, when a primary current is applied to the outer coil and the inner coil, magnetic fluxes generated in the outer coil and the inner coil are formed in the same direction.
    • 无线充电器以无线方式(非接触式或非接触式)对便携式电子设备的蓄电池充电,使得充电效率的变化不会严重,尽管蓄电池被放置在无线充电器的任何位置。 无线充电器设置有用于产生磁场的初级线圈,以便通过与次级线圈的电感耦合为具有次级线圈的被摄体充电。 初级线圈包括以预定线圈数和预定尺寸布置的外线圈; 以及布置成包括在外部线圈内部的至少一个内部线圈。 外部线圈和内部线圈被布置成使得当初级电流施加到外部线圈和内部线圈时,在外部线圈和内部线圈中产生的磁通在相同方向上形成。
