Problems solved by technology

[0004] However, since a conventional power switch is used to switch between the main input terminal and the standby input terminal, where the main input terminal may correspond to the main power supply system and the standby input terminal may correspond to the standby power supply system, in ICT equipment, the arc-generating high probability
This will seriously affect the reliability of ICT equipment and cannot meet high reliability requirements

Abstract

A switching arrangement for switching between two inputs is disclosed herein. The switching arrangement include a first semiconductor switch, a first mechanical switch, a second mechanical switch, thesecond mechanical switch being connectable to the main or backup input, and a controller being coupled to the first semiconductor switch, the first mechanical switch and the second mechanical switch;wherein the controller is configured to generate control drive signals for the first semiconductor switch, the first mechanical switch and the second mechanical switch, the control drive signals being configured to switch off the first mechanical switch at zero voltage, and switch the second mechanical switch from the main input to the backup input or from the backup input to the main input at zero current; the second mechanical switch is switched to the backup input or the main input while the first mechanical switch is off.

Description

technical field [0001] The invention relates to the field of power switches. More particularly, the present invention relates to a switching structure switching between a main input terminal and a standby input terminal, an information and communication technology (ICT) device, and a system and method for controlling the switching structure. Background technique [0002] With the development of information and communication technology (ICT for short), ICT equipment integrates more and more functions, and the electric power required by the ICT equipment increases day by day. In order to achieve high reliability and high availability of ICT equipment, not only the power supply system is used for backup, but also multiple power supply units (PSUs) in the ICT equipment are also used for backup, for example, N+N backup configuration , where N is the number of PSUs used for backup. [0003] As the electric power of ICT equipment increases day by day, it can be implemented throug...
