ABSTRACT
This article presents information on the uninterruptible power system (UPS) used in preventing the devastating consequences of power disturbances. A UPS performs two primary and complementary functions. It conditions incoming power to smooth out the sags and spikes common on the grid and other primary sources of power. It also provides ride-through power to cover for sags and short-term outages by dynamically selecting and drawing power from the grid, batteries, backup generators and other available sources. There are three key types of UPS. Standby UPS are an economical solution for applications tat need only minimal power protection. With a standby UPS, the protected equipment runs off normal utility power until the UPS detects a problem. Line-interactive UPS regulate voltage by boosting input utility voltage up or moderating it down as necessary before allowing it to pass to the protected equipment. Online UPS continuously condition incoming power to deliver clean, perfect sine wave power for protected equipment. Online UPS completely isolate equipment from raw utility power and all its irregularities. Advancements in computer chips and other components have dramatically increased the capabilities of UPS while reducing heat output and cost.
