Electricity products are vulnerable to sudden power outages. Power outages may be short-lived, only 1/10 seconds, but they can be destructive for electronics. In order to prevent this from happening, uninterruptible power supplies are widely used in computer systems, communication systems and other electronic devices. An uninterruptible power supply converts alternating current into direct current and then charges the battery. In this way, in the event of a power outage, the battery can make up for the intermission of the power outage.
