Firstly, when connecting the computer UPS uninterruptible power supply, the following points should be noted:

Insert the three hole plug on the body of the UPS power supply into the socket of the mains power supply, turn on the UPS power switch, and let the UPS power supply work normally. Then plug the power cord plugs of the computer host and monitor into the sockets behind the UPS power supply

Parallel DC stabilized power supply is a common power supply equipment, usually used to provide stable DC power for electronic devices. It has many advantages and some disadvantages, which will be detailed in this article.Firstly, let’s take a look at the advantages of parallel DC stabilized power supply.

The core characteristics of SPWM inverters are reflected in the following aspects: Simplified control structure: The main circuit of this type of inverter usually only contains one controllable power link, with fewer switching elements, which greatly simplifies the structure of the control circuit. In addition, an uncontrollable rectifier is used on the rectification side, which

There are three common types of high-frequency machines. In the late 1990s, one type added a BOOST boost chopper circuit to the SCR rectifier backend to boost the DC to the voltage required for UPS output, thus eliminating the need for an output transformer. It can be simply understood as replacing the AC boost of

The working process of an online UPS is that when the power grid is supplying power normally, the AC power is input into the transformer, and on the one hand, it is charged by the charger to the battery, and on the other hand, it is converted into DC by the rectifier and sent to

The so-called dynamic UPS refers to a device that relies on kinetic energy to achieve uninterrupted power supply, which is an early device that uses diesel generators, electric motors, and generator sets to convert electrical energy. Its structure is shown in Figure 1-1. When the power grid supply is normal, AC power drives the AC

The working process of backup UPS is: when the power supply of the grid is normal, on the one hand, the grid charges the battery pack through the transformer to the charger; On the other hand, it is supplied to the load through the transformer and bypass switch (K connected to point B). The current
