Description
technical field [0001] The present invention relates to the technical field of power supply, and more specifically, to a power supply device and electronic equipment. Background technique [0002] For some electronic devices, such as a lawn pusher powered by 36V, since its usage scenario is outdoor use, its power supply needs to be powered by a battery. In order to improve its cruising time, two battery packs are usually used to power it, and when one battery pack is exhausted, it is switched to another battery pack for power supply. In the power supply of the battery pack, it is usually to switch the power supply circuit of the battery pack by switching the power tube. During the switching process, mutual backflow of current in the link may occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a power supply device and electronic equipment for the above-mentioned technical defects of the prior art. [0004] T...
