Abstract

The present invention relates to a charging device. The charging device includes an input terminal, a power conversion unit, an output triac, a control unit, and a first power supply. The power conversion unit is coupled between the input terminal and the output terminal, and the triac is bidirectional. The AC switch is coupled between the input end and the power conversion unit, the control unit includes a sensing unit and an optocoupler, the sensing unit is coupled between the output end and the triac, and the optocoupler is coupled to the sensing unit Between the three-terminal bidirectional AC switch, the first power supply is coupled to the optocoupler and the sensing unit. When the sensing unit senses that the output end is coupled to the device to be charged, the power supply circuit is turned on, and the power conversion unit works. The present invention utilizes the settings of a three-terminal bidirectional AC switch (TRIAC) and an optocoupler, and senses whether the device to be charged is removed as a criterion for judging whether to cut off the input current, so that when the device to be charged is not coupled to the charging device, it will not Consumes electricity.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging device with zero energy consumption when no device to be charged is coupled. Background technique [0002] The general DC / AC adapter is the most important charging method and equipment for electronic chargers on the market. Due to the increasing awareness of environmental protection, such charging devices still consume a lot of power when plugged into an AC outlet without charging, resulting in energy waste. Therefore, how to achieve zero current consumption (power) when the charging device is not charging has become a problem to be solved in the industry. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a charging device that utilizes a triac (TRIAC) and an optocoupler together with peripheral application circuits to achieve zero power consumption when not charging. [0004] In order to achieve the above obje...
