Embodiment Construction

[0052] In order to realize the hot-swappable function of the centralized bypass module, that is to achieve the peer-to-peer relationship between the centralized bypass module and the power module in the rack, and truly realize the modularization of the UPS system. This makes it easy to replace the centralized bypass module like replacing a power module once the centralized bypass module fails. The present invention constructs a modular UPS system, such as figure 2 The logic diagram of Embodiment 1 of the modularized UPS system of the present invention is shown, the modularized UPS system includes: a plurality of power modules 1, ..., N (N is a natural number greater than 1), a centralized bypass module U and a monitoring module M , wherein the monitoring module M is used to monitor the power modules 1, ..., N and the centralized bypass module U, specifically including two aspects: one is the collection of working status information of each module, such as input voltage, outpu...

Abstract

The invention discloses a modularized uninterruptible power supply (UPS) system and a power supply method thereof. The modularized UPS system comprises a plurality of power modules, a concentrated bypass module and a monitoring module for monitoring the power modules and the concentrated bypass module, wherein the monitoring module is in communication connection with the plurality of power modules and the concentrated bypass module directly; the concentrated bypass module comprises a controllable rectifier, a ready switch and a processor; the controllable rectifier is used for rectifying bypass input voltage when the concentrated bypass module supplies power for load; the ready switch is used for receiving a hot plug signal of a user; the processor is used for blocking a driving signal output to the controllable rectifier when the ready switch is in a unready state. By implementation of the technical scheme of the invention, the on-line hot plug function of the concentrated bypass module is realized, the situation that the concentrated bypass module becomes the single-point fault point of the system can be avoided, and the condition that main and bypass are communicated can be avoided during replacement of the concentrated bypass module due to fault.

Description

technical field [0001] The invention relates to the field of uninterruptible power supplies, in particular to a modularized UPS system and a power supply method thereof. Background technique [0002] The application of traditional tower UPS (uninterrupted power supply, uninterruptible power supply) system is limited due to its low reliability, difficult expansion and maintenance. With the development of science and technology, referring to the design concept of high-frequency switching power supply system structure, a modular UPS system composed of functional modules came into being. The modular UPS system is based on multi-module parallel connection, and realizes online hot swap of power modules. [0003] For UPS users, the advantages of modular UPS are mainly reflected in the following aspects: [0004] 1. Multi-module redundancy can be realized to improve the reliability of power supply. When multiple UPS modules are connected in parallel to supply power to the load, e...
