Uninterruptible power supply (UPS) can use the battery to provide backup power for other AC electrical equipment when the mains fails.
Uninterruptible power supplies are divided into two categories: the first is called standby or offline UPS. Under normal circumstances, a standby UPS acts as an electrical middleman: it plugs into a wall outlet and distributes AC power from the outlet to other electrical equipment connected to it. In addition to distributing power, UPS units usually provide surge protection, but the uninterruptible power supply does not really work until the power is cut! Once the current is detected to fluctuate or stop flowing, the power inverter of the backup UPS will immediately turn on to convert the DC power in the battery to AC power, thereby providing backup power for the equipment under the protection of the UPS.
The second type of uninterruptible power supply is called continuous or online UPS. The function of continuous UPS is much more complicated than that of standby UPS. Continuous equipment does not distribute AC power from a wall outlet like a backup UPS, but runs equipment powered by its battery, and then the battery is continuously charged. Continuous UPS does not need to switch it to battery mode, which means there is no time delay in the event of a mains interruption. Therefore, continuous UPS is mainly used to process critical data or extremely sensitive components.
Using UPS with computer or home theater equipment is the best way to prevent data loss and damage caused by power failure!

High-frequency inverter uses high-frequency DC/AC conversion technology to convert low-voltage DC into high-frequency low-voltage AC. After being boosted by a high-frequency transformer, the high-frequency rectifier filter circuit rectifies it into a
