Problems solved by technology

[0003] 1. Waste of electric energy is not conducive to energy saving and emission reduction
[0004] 2. If the power supply is not cut off, the inside of the charger will be charged for a long time, which will cause the electronic equipment to be fatigued for a long time, shorten its service life, and even reduce the insulation level
[0005] 3. Cause the product to be charged frequently and shorten the service life of the product battery

Abstract

The invention discloses a charger without standby power consumption, comprising a rectifying and filtering unit, a power conversion control unit, an output rectifying and filtering unit, a current sampling unit, a signal amplification unit, a central control unit and a switching control unit, wherein the switching control unit comprises an optical coupler, a thyristor and a light touch press key. The work of the charger is realized by pressing the light touch press key and charging conditions of equipment to be charged can be monitored in real time by the central control unit in the process of charging, so that an alternative current power supply can be automatically cut off after the equipment to be charged is completely charged. With the adoption of the charger, the charger does not have the standby power consumption, the electric energy is effectively saved, the service life of the charger is prolonged, and the use safety of the charger is improved; meanwhile, the battery of the equipment to be charged is prevented form being frequently charged for a plurality of times and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to a charger with a USB interface, in particular to a charger with zero standby power consumption. Background technique [0002] Portable products that are widely used at present, such as mobile phones, notebook computers, portable electric tools, etc., are equipped with chargers. When charging, many people do not take the charger off the power socket as soon as it is fully charged, and often wait to think of it. When it is removed, it will cause the following problems: [0003] 1. Waste of electric energy is not conducive to energy saving and emission reduction. [0004] 2. If the power supply is not cut off, the inside of the charger will be charged for a long time, which will cause the electronic equipment to be fatigued for a long time, shorten its service life, and even reduce the insulation level. [0005] 3. The product is frequently charged many times, which shortens the service life of the product battery. Contents of...
