Abstract

The invention relates to a modular uninterrupted power supply (UPS) and a control method of a charger thereof. The modular UPS comprises a battery and at least one charger, wherein the at least one charger is connected with one another in parallel to charge the battery. After being started, each charger performs the following steps of: A, detecting the charging voltage and the charging current per se; B, judging whether the detected charging voltage is more than a preset first voltage value and whether the charging current is less than a preset first current value, and if the detected charging voltage is more than the preset first voltage value and the charging current is less than the preset first current value, executing step C; C, judging whether the charger is a preset main charger, and if the charger is not the preset main charger, turning off the charger. Due to the modular UPS and the control method of the charger of the modular UPS, the chargers of modules of the modular UPS can be connected with one another in parallel to charge the battery; and the structure is simple.

Description

technical field [0001] The invention relates to a UPS power supply, more specifically, to a control method for a modularized UPS and a charger thereof. Background technique [0002] UPS (Uninterruptible Power Supply, uninterruptible power supply) is widely used in telecommunications, finance, government, manufacturing and many other industries. work or loss of data. In computer systems and network applications, it mainly plays two roles: one is emergency use, preventing sudden power failure from affecting normal work and causing damage to the computer; "Power supply pollution" such as low voltage, wire noise, and frequency offset improves power quality and provides high-quality power for computer systems. [0003] In the traditional UPS configuration, one UPS is equipped with a set of batteries. In charging mode, a charger can charge a set of batteries. [0004] Modular UPS can be removed and installed at will without affecting the operation and output of the system when ...
