Abstract

The invention discloses a power supply device, a charging system and electronic equipment. The power supply device comprises: a first protocol communication module, which is used for acquiring the adaptive voltage information of an electric device; a first magnetic terminal, which is connected with the first protocol communication module, wherein the power supply device is connected with a power utilization device through the first magnetic terminal and supplies power to the power utilization device; and a buck-boost module, which is separately connected with the first protocol communication module and the first magnetic terminal, and used for setting the output voltage of the first magnetic terminal according to the acquired adaptive voltage information. In one embodiment of the invention, the output voltage is set through the buck-boost module, and the problem that the power supply device cannot be charged due to mismatching between the voltage of the power supply device and the voltage of the power utilization device can be solved.

Description

technical field [0001] The present invention relates to the technical field of charging, and more specifically, to a power supply device, a charging system and electronic equipment. Background technique [0002] Existing terminal charging mainly includes three methods: wired charging, wireless charging and magnetic charging. Wired charging is a mature technology, cost-effective, and stable, and is currently the most common charging method. The popular wireless charging benefits from the convenience of charging, and it can be charged without using a data cable. Magnetic charging is mainly used in low-power devices such as smart wearables. [0003] In the existing magnetic charging, the mechanical terminals are attracted to each other, and the two terminals can be attracted together for charging when they are close to each other. However, magnetic charging has obvious defects. First of all, the charging voltage range of some charging terminals is often very small, and some a...
