Problems solved by technology

[0003] However, the arrangement of the conductive terminals inside the charger and the portable electronic device must be equipped with a port, dust and foreign impurities are easy to invade, and it is easy to cause poor contact between the terminals. In particular, different types of portable electronic devices of different brands are currently Devices are equipped with different chargers, so that each person may have multiple chargers, especially for home users, a large number of chargers bring great inconvenience to the family, and at the same time, due to the need for multiple chargers when going out , which makes it inconvenient to carry
If the user needs to replace or purchase a portable electronic device, he must purchase a matching charger, and the original charger causes a waste of resources

Abstract

The invention discloses a wireless charging method. A wireless charger comprises a wireless charging emitting end and a wireless charging receiving end. The method is characterized by comprising the following steps of: (1) arranging a radiating shell at the wireless charging emitting end; (2) arranging a magnetic plate on the inner surface of the radiating shell to generate magnetic induction intensity; (3) arranging at least three induction coils, wherein the induction coils are arranged in a triangular form; (4) arranging a power adapter which is connected with the induction coils through leads and is used for supplying a working power supply to the induction coils; and (5) arranging an NTC (Negative Temperature Coefficient) control device which is connected with the coils and a charger control circuit and is used for controlling the magnitude of charging current by monitoring the temperature of a magnetic core. The invention further discloses a wireless charger for implementing the method. The method and the charger provided by the invention have the advantages of working stability, high working efficiency, high reliability, and capability of supporting high-power charging equipment.

Description

technical field [0001] The invention relates to the field of electronic information, and more to the field of power charging, in particular to a wireless charging method and a wireless charger for realizing the method. Background technique [0002] Currently, portable electronic devices, such as MP3 players, mobile phones, PDAs, etc., have rechargeable batteries therein so that users can use the portable electronic devices while moving. This type of portable electronic device is separately equipped with a charger specially used for charging the rechargeable battery, and the charger is connected to a common power source through a cable and then connected to the rechargeable battery for charging. In order for the charger to provide charging current to the rechargeable battery of the portable electronic device, the charger must be electrically connected to the rechargeable battery of the portable electronic device. In order to electrically connect the charger with the portable...
