Brasilia UPS power supply uninterruptible power supply system

Uninterruptible power supply (UPS) systems are used to provide uninterrupted, reliable, and high quality power for these sensitive loads. Applications of UPS systems include medical facilities, life supporting systems, data storage and computer systems, emergency equipment, telecommunications, industrial processing, and on-line management systems.

However, during transmission and distribution, it is subject to voltage sags, spikes and outages that can disrupt computer operations, cause data loss and damage equipment. The uninterruptible power supplies protect the connected equipment from power problems and provide battery backup during power outages.

UPS systems are used to provide reliable and uninterruptible power for critical loads by transferring power supply from the utility to backup energy storage when a power disruption occurs. Rechargeable batteries are always the primary choice owing to their comparatively high energy density.

For large power supplies, a dynamic uninterruptible power supply (DUPS) can be used. The synchronous motor/alternator is connected to the mains power supply through a choke. Flywheel stored the energy. In the event of a line failure, the stored current control keeps the load driven until the power of the flywheel is exhausted.

Online/double-conversion UPS: With an online UPS, the battery is always connected to the inverter, so no power transfer switch is required. When power is lost, the rectifier simply exits the circuit to keep the battery power stable and holding.

The line UPS puts the inverter on the interactive UPS line and switches the current path of the battery DC to supply when power is lost from normal charging mode. In a standby (“offline”) system, the load is driven by the direct input supply, and the backup supply circuit is applied only in case of supply power failure.
