Voltage Control Techniques in Uninterruptible Power Supply Inverters: a Review
نویسندگان
چکیده
Uninterruptible power supply (UPS) systems are required for supplying sinusoidal output voltage for linear and nonlinear loads. They must be highly reliable and fast in dynamic response. Many control strategies have been applied to UPS inverters. The basic objectives of UPS control systems are tracking ability and robustness. Generally, the tasks of output voltage control for UPS inverters are providing fast dynamic responses and maintaining a perfect sinusoidal voltage waveform even with nonlinear or changing loads. To achieve these aims, many controllers have been proposed in the literature. In this paper a comprehensive review of the control techniques of UPS systems with advantages and disadvantages of each is carried out. Copyright © 2011 Praise Worthy Prize S.r.l.

A Review on Optimization of Energy by Using Pwm Inverter
An important part of uninterruptable power supply is the DC to AC inverter which converts the DC voltage from a battery to an AC voltage that is required to operate electronic circuits. These inverters are bulky in nature & consume most of the power. Therefore power available at the output of inverter is less. So it is the goal of this paper to develop a DC/AC inverter capable of producing a pu...
متن کاملPerformance Analysis of Multilevel Inveter
The power electronics device which converts DC power to AC power at required output voltage and frequency level is known as inverter. Multilevel inverter as compared to single level inverters has advantages like minimum harmonic distortion, reduced Electromagnetic interference (EMI)/Radio frequency interference (RFI) generation and can operate on several voltage levels. A multi-stage inverter i...
متن کاملPerformance Improvement of LFFC Schemes Base on B- Spline Networks for UPS Inverters
Although Learning-based control method base on B-Spline Network (BSN) together with PD controller presents an excellent steady-state performance for Uninterruptible Power Supply (UPS) Inverters but it may not achieve high dynamic performance under non-periodic disturbances, which can be inappropriate for high performance UPSs. To further reduce the transient errors, in this paper a simple desig...
متن کاملA simplified control strategy for single-phase UPS inverters
Though there are many strategies to control single-phase uninterruptible power supply (UPS) inverters, they suffer from some drawbacks, the main being complexity. This paper proposes a simple dual-loop controller for the single-phase UPS inverter with the LC filter. The suggested control scheme uses the capacitor current as the feedback signal in the inner current loop. No fictitious phase gene...
متن کاملModulation Techniques for Three-Phase Four-Leg Inverters
Three-phase four-leg inverters are typically employed to supply unbalanced loads avoiding the use of a transformer. Usually, the inverter control is performed by modulation techniques, such as the threedimensional one, requiring complex mathematical algorithms. The paper suggests a different approach, based on the separation of the control of the fourth leg from that of the other phases, allowi...
