Abstract
Content

Virtually all businesses and industries are vulnerable to electric power disturbances such as outages, sags, swells, and harmonics. These problems are less of an issue for data centers, protected behind their walls of Uninterruptible Power Supply (UPS) systems. But the typical battery-backed UPS is too fragile for use in less protected environments. UPS batteries must be maintained in a narrow temperature range and fail prematurely when subjected to a steady diet of step loads and motor drives. About six years ago, flywheel-based UPS products became commercially available. These devices store energy as rotational inertia, and are rugged enough to survive on the factory floor. However, flywheels have relatively short ride-through energy and are best-suited for use in locations with backup generators.
