Problems solved by technology

However, the USPS power supply is mostly directly connected to the load with a single power supply. For communication systems that require redundant hot-swappable power supply, some industrial controls, and some unattended equipment, a single USPS power supply is not competent.

Embodiment Construction

[0025] The present invention is further described in conjunction with the accompanying drawings of the embodiments.

[0026] figure 1 , figure 2 The redundant uninterruptible switching power supply system shown includes: two USPS power supplies (101A, 101B), output distribution unit (501), power monitoring unit (301), battery monitoring unit (202), RS232 or USB interface circuit ( 302) and the sound and light state prompt unit, etc. All external connections of the two USPS power supplies (101A, 101B) are implemented in a hot-swappable manner.

[0027] The two sets of main output voltages (102A, 102B) of the two USPS power supplies (101A, 101B) respectively enter the output distribution unit (501), and are isolated, connected in parallel, divided into circuits, and protected by the output distribution unit (501). Item connection processing, and then output to the load (502A, 502B). The output distribution unit (501) is outputted from one or more channels after being isolat...

Abstract

In the present invention, two main voltage outputs of two uninterruption switching powers are sent to output distribution unit separately and then to send them to a numbers of loads by take-off outputs at the same, battery is charged protectively by the two powers. The two power can pick up energy from the battery set and supply the power continuously for the loads when power is off. The two are at de-rate operation if both are normal and the other one outputs all required energy to the loads if one power is closed because it is fault or AC power for it is off.

Description

technical field [0001] The invention relates to combined switching power supply technology, specifically a dual uninterruptible switching power supply (Uninterruptible Switching Power Supply abbreviated as USPS) redundant output method, and a redundant hot-swappable uninterruptible switch composed of two uninterruptible switching power supplies. Intermittent switching power supply system to meet the needs of systems or equipment that are highly sensitive to the grid and need to run uninterrupted for a long time. technical background [0002] With the vigorous development of the IT industry represented by the Internet, higher requirements are put forward for energy. A considerable number of network communication devices require 7×24 hours of continuous work without interruption, so various devices will adopt redundant methods. In addition to the redundancy of the hardware configuration, the redundancy of the power supply system is essential. Therefore, from equipment investm...
