Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a self-power supply circuit and a wearable device with the self-power supply circuit. Background technique [0002] With the continuous development of power electronics technology and the continuous improvement of production technology, various electronic devices emerge in an endless stream, especially smart wearable electronic products. Current wearable electronic products usually require smaller volume and weight, which makes their own battery capacity very limited, resulting in frequent charging of wearable electronic products, which seriously affects the user experience of consumers. [0003] Therefore, during the process of designing the charging circuit of wearable electronic products, the inventor found that at least the following problems existed in the prior art: [0004] Existing wearable electronic products have limited battery capacity, which leads to frequ...
