How does the uninterruptible power supply work in theory?
How does an Uninterruptible Power Supply work? An Uninterruptible Power Supply (UPS) is a device connected between the power source and a computer to ensure that electrical flow is not interrupted. UPS devices use batteries to keep the computer running for a period of time after a power failure. It is not to be confused with standby generators which do not provide protection from a momentary power interruption, or which may result in a momentary power interruption when it is switched into service, whether manually or automatically. UPS devices usually provide protection against power surges, brownouts and line noise as well. The UPS consists of three main components: 1. Rectifier: Stores line power in the battery after converting the AC power into DC power. Power disruptions only affect the battery charging process because the battery is being charged by the rectifier. 2. Battery: Stores the power for use when the power source is interrupted, and determines the length of time the UPS w
