What is an uninterruptible power supply (UPS)?
Uninterruptible power supplies (UPSs) deliver clean, conditioned, and reliable power to critical loads such as communication systems, network servers, medical equipment, etc. . Typically, the UPS provides unity power factor, high efficiency, high reliability, low cost, and continuous power supply, irrespective of the grid conditions [2, 3, 4].
What is a high-frequency isolated online UPS system for low power applications?
This paper proposes a high-frequency isolated online UPS system for low power applications. The proposed UPS consists of a single-stage AC-DC converter, boost DC-DC converter, and an inverter. The single-stage AC-DC converter provides galvanic isolation, input power factor correction, and continuous conduction of both input and output current.
How is active and reactive load distribution between N paralleled single-phase uninterruptible power supply (UPS) inverters?
Abstract: The active and reactive load distribution between n paralleled single-phase uninterruptible power supply (UPS) inverters is equalized by virtue of n-1 load-sharing control loops. The approach permits the construction of UPS systems of any desired power rating at maximum utilization of the power components.
What is output phase regulation for paralleled uninterruptible power supply system?
Output phase regulation for paralleled uninterruptible power supply system. When the active circulating current and reactive circulating current in the parallel system are detected in the control system, the increase in the inverter output voltage phase angle is calculated according to Eq. (15.41).
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 a 0 kVA ups?
Offline UPS is usually between 0 and 10 kVA. This solution covers mainly power discrete solutions and is usually divided into low frequency and high-frequency transformer-based systems. It is used when AC line voltage is present a relay bypasses the inverter, which remains off. The battery charger operates to maintain full charge.
