New Electronic Product-Wireless Charger

      First, guided positioning (magnetic attraction): that is, one-to-one fixed position charging is used to guide the placed charging device and achieve accurate calibration. The advantage of this calibration method is simple, but it requires a series of magnets in the charging device. The attracted material, therefore, the power loss associated with eddy currents (and thus increased temperature) will be attracted to the magnetic attractor. Second, free positioning (with a movable primary coil): also a one-to-one charging device that can be positioned for charging. This method requires a mechanically movable primary coil, which is tuned to be coupled to the position of the charging device, however, Movable mechanical parts tend to reduce the reliability of the system. In addition, the control of the primary coil motor for multiple devices that are charged is complicated and expensive. Third, free positioning (coil array): allows multiple devices to charge without considering their position. Compared with the above two methods, this calibration method is based on more expensive and more complicated winding structure and control electronics. The price provides more user-friendliness.
