Abstract

The invention provides an uninterruptible power supply UPS device which comprises an uninterruptible power supply UPS branch, a bypass and a controller, wherein the UPS branch is in parallel connection with the bypass; the UPS branch comprises a rectification unit, an inversion unit and a storage battery; the input end of the rectification unit is connected with an alternating current power supply; the input end of the inversion unit is connected with the output end of the rectification unit; the output end of the inversion unit is connected with a load; the storage battery is jointed between the output end of the rectification unit and the input end of the inversion unit; the bypass comprises a bypass switch; the two ends of the bypass switch are respectively connected with the alternating current power supply and the load; the controller is connected with the bypass switch, the rectification unit and the inversion unit; the controller is used for controlling the rectification unit and the bypass switch to switch on and the inversion unit to switch off when the alternating current power supply is normal; or the controller is used for controlling the inversion unit to switch on and the rectification unit and the bypass switch to switch off when the alternating current power supply is abnormal. The UPS device provided by the invention is capable of guaranteeing the cruising power of the UPS device and supplying high reliability of the uninterruptible power supply of the UPS device.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a UPS device for uninterrupted power supply. Background technique [0002] With the development of economy and society, the problem of power supply reliability will not only bring great economic losses to the industry, such as shutdown and restart leading to increased production costs, damaged equipment, scrapped semi-finished products, reduced product quality, and caused marketing difficulties and damage The image of the company and the good business relationship with users, etc., will also bring harm to the equipment of important electricity-consuming departments such as medical care, cause serious production and operation accidents, and at the same time cause more social impacts, so the economic losses caused and the society The impact is huge. [0003] Uninterrupted power supply (uninterrupted power supply, UPS) came into being. It is a system device that connects the...
