Uninterruptible Power Supply (UPS)

A UPS, or a uninterruptible power supply, is a device used to backup a power supply to prevent devices and systems from power supply problems, such as a power failure or lightning strikes. A UPS can help prevent power supply problems that can often occur on a production site, such as an instantaneous voltage drop and a power failure.

Uninterruptible Power Systems

High-power UPS systems use thyristors with forced commutation circuits as the power switches. Systems with ratings less than 200 kVA now use power transistors or insulated-gate bipolar transistors as the power switches. Fig. 63 shows a circuit diagram for a UPS system using a three-phase, pulse-width-modulated inverter supplied from a battery and feeding a transformer

Overview of Uninterruptive Power Systems (UPS)

In the normal mode, the load is directly supplied with the utility power supply at the same time the charger charges the battery. In the event of a blackout, the battery will supply power to the inverter that will supply AC power to all connected loads. The transfer switch is used to switch between the utility power supply and the inverter.

6 FAQs about [Power Engineering AC Uninterruptible Power Supply]

What is an uninterruptible power supply system?

Uninterruptible Power Supply System When utility mains are not available, electricity can be supplied from a source such as a standard connected equipment UPS, which provides power supply. UPS is mostly used for critical loads and is kept between commercial utility mains.

What is an uninterrupted power supply (UPS) system?

Abstract. In the modern world, when there is a power outage or a power failure, telecommunication systems, computer systems, and many other critical equipment, such as medical equipment, require uninterrupted power to support their operation. Uninterruptible power supply (UPS) systems are used for this purpose.

How do uninterruptible power supplies (UPS) mitigate voltage sags?

Uninterruptible power supplies (UPS) mitigate voltage sags by supplying the load using stored energy. Upon detection of a voltage sag, the load is transferred from the mains supply to the UPS.

What is backup uninterruptible power supply?

15.1.3.1. Backup uninterruptible power supply Fig. 15.2 shows the structure of the backup UPS. The backup UPS directly supplies power to the load from the grid when the utility power is normal. At this time, the inverter of the UPS does not work, and the grid charges the battery if the battery is not fully charged.

What is unified control scheme for uninterruptible power supply system?

Conceptual diagram of unified control scheme for uninterruptible power supply system. Because of the three-phase four-wire configuration, the control for each phase in both the PWM rectifier and inverter can be decoupled. Therefore, a single-phase independent control approach can be adopted.

What is the input power supply for an AC-AC UPS?

An AC-AC UPS is the optimum option for backing up devices with an AC input power supply. During normal operation, the input power supply bypasses the UPS and is output as-is.
