Problems solved by technology

[0003] However, after the UPS system is switched to the bypass power supply through the triac, the bidirectional thyristor is in the load mode for a long time and overheats, and the overheating of the bidirectional thyristor will cause the triac to fail. Damaged, resulting in the inability of the UPS system to provide uninterrupted power supply, making the UPS system have a problem of low reliability when switching to bypass power supply

Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0045] The power supply mode switching method provided by the embodiment of this application can be applied to such as figure 1shown in the application environment. Wherein, the controller 101 communicates with the UPS system 102 through the network. The controller 101 can receive a trigger instruction of the UPS system 102, and control the power supply mode of the UPS system 102 to switch from the inverter power supply mode to the bypass power supply mode according to the trigger command. Wherein, the controller 101 may be a controller of an uninterruptible power supply...

Abstract

The invention relates to a power supply mode switching method and system, a controller and a storage medium. The method comprises the following steps: receiving a trigger instruction sent by an uninterruptible power supply (UPS) power supply system; determining the running state of a bidirectional silicon controlled rectifier static switch of the UPS system and the power supply state of the UPS system according to the trigger instruction; when the bidirectional silicon controlled rectifier static switch of the UPS system is in an off state and the power supply state of the UPS system is in a normal state, the bidirectional silicon controlled rectifier static switch is controlled to be switched on, so that the power supply mode of the UPS system is switched from an inversion power supply mode to a bypass power supply mode; and under the condition of determining that the power supply mode of the UPS power supply system is switched to the bypass power supply mode, controlling the relay to be switched on and controlling the bidirectional silicon controlled rectifier static switch to be switched off, so that power is supplied to load equipment of the UPS system through the relay. By adopting the method, the reliability of bypass power supply of the UPS system can be improved.

Description

technical field [0001] The present application relates to the technical field of uninterruptible power supply UPS power supply, in particular to a method, system, controller and storage medium for switching power supply modes. Background technique [0002] As computers and other high-precision equipment have higher and higher requirements for power supply reliability and power supply quality of power supply systems, uninterruptible power supply (Uninterruptible Power System, UPS) power supply technology has emerged. UPS power supply technology can provide voltage signals without clutter interference for computers and other high-precision equipment. And the UPS power supply technology can switch to the bypass power supply of the UPS system when the inverter output end suddenly loses power, so as to ensure the uninterrupted power supply of the UPS system. [0003] However, after the UPS system is switched to the bypass power supply through the triac, the bidirectional thyrist...
