Description

technical field [0001] The invention belongs to the technical field of chargers, and in particular relates to a solar charger control circuit and a solar charger. Background technique [0002] The existing charger is generally an intermediate conversion device, which converts AC power into DC power and stores it in the battery of mobile phones and other equipment. It has the advantages of convenient use and simple operation. But this kind of charger is only used as a transmission medium between the power supply and equipment such as mobile phones. When people go out or have no power supply indoors, people cannot charge equipment such as mobile phones in time. It is highly dependent on the power supply, and the charger cannot be used after disconnecting from the power supply, which affects the normal use of mobile phones and other equipment. [0003] In response to the above problems, people have invented a mobile charger, which can be fully charged when there is a power sup...

Problems solved by technology

[0005] (1) The utilization rate of solar energy is not high, that is, the maximum power output cannot be achieved in many cases;

[0006] (2) If the load changes suddenly, the voltage of the solar panel will be pulled down suddenly, causing the MCU to fail to operate normally. At this time, even if the solar panel produces electricity normally, the solar charger cannot output energy
