Free QuoteUninterruptible 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.
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.
Soft-switching uninterruptible power supplies The traditional back-to-back converter based on silicon devices uses a hard switching mode. Its switching frequency is limited, resulting in larger filters and higher audio noise. Soft switching technology can reduce the switching loss of power semiconductor devices and improve conversion efficiency.
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.
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.
Diagram of output voltage regulation for paralleled uninterruptible power supply system. When the control system detects the active circulating current and reactive circulating current in the parallel system, the increase in the inverter output voltage amplitude is calculated according to Eq. (15.40).
