What is an uninterruptible power supply (UPS) system?
Power distortions such as power interruptions, voltage sags and swells, voltage spikes, and voltage harmonics can cause severe impacts on sensitive loads in the electric systems. Uninterruptible power supply (UPS) systems are used to provide uninterrupted, reliable, and high-quality power for these sensitive loads.
Why do we need uninterruptible power supplies?
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.
Can uninterruptible power supplies be used as a hybrid storage system?
Uninterruptible Power Supplies with hybrid storage system Uninterruptible power supplies with batteries as storage source provides good performance during grid interruption and blackout by suppling instant backup energy. However batteries cannot provide backup for a very long period of time and have limited charge/discharge cycles.
What happens if power supply stops suddenly?
If power supply to devices stops because of an instantaneous voltage drop or a power failure, devices such as PCs or registers shut down abnormally, which can damage hard disks and corrupt the data. A UPS can help prevent such power supply problems.
What happens when a UPS fails?
During normal operation, the input power supply bypasses the UPS and is output as-is. When a UPS fails or experiences a power failure or instantaneous voltage drop, it changes to inverter operation and supplies power from its internal battery.
How to regulate the output of a UPS system?
Generally the output of the UPS system must be regulated sinusoidal with low total harmonic distortion (THD), irrespective of the changes in the input voltage and abrupt changes in the load connected to the system .
