What is uninterruptible power supply (UPS)?
Uninterruptible Power Supplies (UPS) have reached a mature level by providing clean and uninterruptible power to the sensitive loads in all grid conditions. Generally UPS system provides regulated sinusoidal output voltage, with low total harmonics distortion (THD), and high input power factor irrespective of the changes in the grid voltage.
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.
What is a single phase high-frequency transformer isolated online UPS?
Conclusions A single phase high-frequency transformer isolated online UPS has been proposed in this paper. A single-stage AC-DC converter provides galvanic isolation, efficient power conversion, and excellent power factor correction. Besides, the AC-DC converter also charges the battery bank of the UPS system during grid mode of operation.
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.
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 .
What is the minimum power factor for UPS?
According to the IEEE standard ANSI/IEEE 446–1987, minimum power factor is 0.8 at the rated load and harmonics content less than 5% is preferred for the input rectifier of the UPS system. Table 8. Typical 3-Ø UPS System Specification by ANSI/IEEE 446–1987 . Fig. 27. Input Voltage and Current waveform.
