Intelligent UPS controller

Abstract

The invention discloses an intelligent UPS controller, which comprises a controller, a switching power supply, a sampling circuit, a storage battery, a charging protection module, an inverter, a transformer and a conversion circuit. The intelligent UPS controller is uniformly controlled by the controller; the structure is greatly simplified; the integration level of a whole system and the working reliability are greatly improved; synchronous conversion of electric supply and a UPS can be effectively achieved through control of the controller; communication between the power supply and a computer is achieved through application of a serial port of the controller; the intelligent UPS controller is more convenient to use by a user; intelligent control on the storage battery is achieved through control of the controller; and compared with a continuous floating charge mode, the intelligent UPS controller has the advantage that the life of the storage battery is effectively prolonged.

Description

technical field [0001] The invention relates to a power supply, in particular to an intelligent UPS power supply controller. Background technique [0002] With the continuous development of society, electrical equipment has higher and higher requirements for power supply quality. In order to ensure the safety of electrical equipment, an uninterruptible power supply (UPS) is highly valued. Among them, the backup square wave output UPS voltage is widely used because of its small size, light weight, relatively cheap price, high operating efficiency and low noise. However, the traditional backup square wave UPS adopts analog circuit control, the structure is complex, it is difficult to upgrade, it is difficult to implement some advanced control algorithms, and there are some shortcomings in performance. For example, the in-phase switching function is not implemented in most analog controls, so there is a danger of short-circuiting the AC during the switching process, which is ...

Problems solved by technology

However, the traditional backup square wave UPS adopts analog circuit control, the structure is complex, it is difficult to upgrade and replace, it is difficult to realize some advanced control algorithms, and there are some shortcomings in performance.

For example, the in-phase switching function is not implemented in most analog controls, so that there will be a risk of short circuit in the AC during the switching process, it is inconvenient to communicate with the computer, and it is impossible to realize real-time monitoring and other defects.
