An uninterruptible power supply system is a system that allows for the normal operation of devices during power surges, including the ability to maintain the operating mode of the device for a while with the central power supply completely turned off.
Uninterruptible power supply is an automatic device that serves to provide equipment connected to the system with uninterrupted voltage within normal limits. These sources may differ in power sizes and schematic base.
Uninterruptible power supply systems are mainly used by consumers for whom the stable operation of the equipment (in any situation) is extremely important. These are people working with computer technology that requires a constant supply of current. For example, Internet providers, which must ensure the high efficiency of servers, medical centers, the equipment of which serves to support the life support of patients, etc.
UPS direct current can be divided into two types. The first is devices capable of independently generating electric current. These include diesel and
gasoline generators, solar power sources, wind towers, etc. The second - devices that give off electricity if necessary. In fact, such systems can be safely called a battery. These include UPS or UPS.
UPS uninterruptible power systems are divided into two classes: online SPB and offline SPB. Today, online systems are more in demand. For example, SPB with a dual voltage conversion system. In this mode, the alternating voltage becomes constant, and the battery is charged. In the event of a disconnection of the flow of electric current or its sharp jump, the opposite effect occurs - direct current is converted into alternating current. The battery in the role of
energy storage is connected between the inverter and the rectifier, performing the opposite action. The quality of the conversion result directly depends on the accuracy of the voltage and sine wave.
Uninterruptible power systems, which are related to offline mode, are installed in parallel with the main electrical network. The input voltage first passes in transit through the filters. In the event of a power failure or its complete absence, they also automatically switch to
batteries. However, with the complete absence of electric current in the network during switching to backup drives for a while, literally a few milliseconds, the voltage disappears altogether. Such
uninterruptible power systems are used in areas that are not so categorical in relation to the short-term disappearance of electric current.
There is another big plus in the possibility of using such equipment. Uninterruptible power supply systems can be designed in such a way that the current supply to the maximum consumption devices is supplied bypassing the UPS, for example, to the main
power supply network
, through automatic switching
systems or gas generators. Accordingly, equipment that is sensitive to power surges (TV, computer, refrigerators, microwave ovens, etc.) will be reliably protected.
