[0002] Most of the existing smart phones are touch screen phones. When the smart phone is charged by the charger, the charger will introduce common mode noise to the smart phone. When the noise on the touch screen is mistaken for a human click operation, it will When the touch screen jumps, that is, the touch screen will move even if it is not touched, or the user clicks on one position on the touch screen, and the touch screen responds at another position, so that the user cannot use the electronic device normally.

The invention discloses a method and an apparatus for controlling charging of a charger, and the charger. The method comprises the steps of receiving a feedback signal from electronic equipment, wherein the feedback signal carriers the current first working frequency of a touch screen of the electronic equipment; determining whether the second working frequency of a voltage reduction module of the charger needs to be regulated to a third working frequency or not according to the first working frequency; and when the second working frequency needs to be regulated to the third working frequency, controlling the voltage reduction module to perform voltage conversion at the third working frequency, and charging the electronic equipment at the third working frequency. By virtue of the technical scheme disclosed by the invention, common-mode noise generated to the touch screen of the electronic equipment can be avoided in the charging period for the electronic equipment by the charger, so that it is ensured that the electronic equipment can be used as normal in the charging period, thereby improving user experience in using the electronic equipment.
Description
technical field [0001] The present disclosure relates to the technical field of chargers, in particular to a method and device for controlling charging of a charger and a charger. Background technique [0002] Most of the existing smart phones are touch screen phones. When the smart phone is charged by the charger, the charger will introduce common mode noise to the smart phone. When the noise on the touch screen is mistaken for a human click operation, it will Sometimes jumping occurs, that is, the touch screen will move even when it is not touched, or the user clicks on one position on the touch screen, and the touch screen responds at another position, so that the user cannot use the electronic device normally. Contents of the invention [0003] In order to overcome the problems existing in the related art, the embodiments of the present disclosure provide a method, device and charger for controlling charging of a charger, so as to avoid bringing common-mode noise to th...
