A dynamic voltage restorer (DVR) is developed to stabilize the three-phase load under sudden grid distortion conditions, including sag, swell and unbalance. The DVR composed of a DC\AC inverter DC-link capacitor regarded as energy storage element. When occurs, instant power compensate or absorb realized by resulted in degenerate stabilization performance poor transient quality load. Hence, cont...

The Quality of the output power from the utilities has become a major concern of the modern industries. These power quality associated problems are voltage sag, surge, flicker, voltage imbalance, interruptions and harmonic problems. These power quality problems may cause problems to the industries ranging from malfunctioning of equipment to complete plant shut down. It has been identified that ...
