Dual-power-supply switching power supply system

Abstract

The invention relates to the technical field of dual-power-supply switching power supply, and discloses a dual-power-supply switching power supply system which comprises a central processing unit, the receiving end of the central processing unit is in signal connection with the transmitting end of a total database, and the receiving end of the central processing unit is in signal connection with the transmitting end of a power supply switching unit. The receiving end of the central processor is in signal connection with the transmitting end of the power control unit. According to the dual-power-supply switching power supply system, the UPS power supply serves as common power, the distribution room power supply serves as standby power, one power supply path is added on the original basis, automatic switching is achieved after one power supply path loses power, and power supply safety of important equipment is guaranteed; the circuit monitoring unit is arranged to detect the power supply circuit in real time, the power supply control unit is controlled to adjust the current and voltage of the circuit, and the power supply monitoring unit is arranged to monitor the power supply of the UPS. The power supply monitoring unit controls the power supply switching unit through the feedback module and the negative feedback compensation module to replace the power supply of the power distribution room.

Description

technical field [0001] The invention relates to the technical field of dual power supply switching power supply, in particular to a dual power supply switching power supply system. Background technique [0002] The UPS output power supply guarantees the safety of power supply, but if the UPS battery is damaged or the UPS host is damaged, it will easily lead to a power outage. At that time, the UPS needs to be manually bypassed to connect to the temporary line, which is time-consuming and laborious. The dual power supply system has always been concerned by various industries at home and abroad. The focus is to play a very important role in areas with high load levels such as process production, medical facilities, large commercial buildings, and telecommunication center buildings. At present, there are two kinds of uninterruptible power systems used in China: ATS and UPS. One requires special technology to judge, identify and switch dual power sources. In addition, the capaci...

Problems solved by technology

[0002] The UPS output power supply ensures the safety of the power supply, but if the UPS battery is damaged or the UPS host is damaged, it may directly lead to a power outage. Time-consuming and labor-intensive, the dual power supply system has always been the focus of various industries at home and abroad, and plays a very important role in areas with high load levels such as process production, medical facilities, large commercial buildings, and telecommunication center buildings.

At present, there are two types of uninterruptible power systems used in China: ATS and UPS. One requires special technology to judge, identify and switch dual power sources. In addition, the capacity of power supply is greatly limited. Therefore, a dual power supply switching power supply system is proposed.
