Problems solved by technology

[0012] The main purpose of the present invention is to provide a parallel uninterruptible power supply system, the parallel uninterruptible power supply system can not only improve the traditional parallel uninterruptible power supply system, which requires external communication ports to enable uninterruptible power supplies to communicate with each other. The slow signal transmission rate will affect the reaction time of the entire parallel uninterruptible power supply system, and it can also solve the problem of signal transmission that needs to be equipped with a communication chip. The price of the communication chip is expensive, which will cause the production cost of the entire product to be too high.

Abstract

This invention relates to one parallel power supply system without stop, which uses first signal of first supplier and second signal of second supplier to connect with connector to make the first control module receive data signals from second power module and second battery module and the second control module receive data signals from first power module and first battery module to make the first and second suppliers connect.

Description

technical field [0001] The invention relates to an uninterruptible power supply system, and more particularly to a parallel uninterruptible power supply system. Background technique [0002] Uninterruptible Power Supply (UPS) is a device connected between the power supply and the load. The power supply can be direct commercial AC power supply or converted alternating current (AC). The main purpose of the uninterruptible power supply system is to provide the energy required for the operation of the load in an emergency when the power supply is abnormal, so as to ensure the normal operation of the load. [0003] In order to protect important electronic equipment more effectively and safely, uninterruptible power supply systems have been widely used to ensure the normal operation of various electronic equipment. Among them, the parallel uninterruptible power supply system is the best choice. [0004] Please refer to FIG. 1, which is a schematic structural diagram of a known pa...
