A Dynamic Voltage Restorer (DVR) based interface scheme for microgrids
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014This paper deals with the issues related to the interconnection between the microgrid and main network. The Dynamic Voltage Restorer (DVR) is proposed as an interface between the main network and microgrid in order to improve reliability and limit fault currents. The performance of DVR is demonstrated during fault conditions in two different locations,

Study on Compensation of Voltage Sag and Voltage Swell by Using DVR (Dynamic Voltage Restorer)
2018 International Conference on Current Trends towards Converging Technologies (ICCTCT), 2018Significant feature for electrical engineering is quality of power in modern days. Due to growing use of solid state, non-linear, power semiconductor switching devices power quality issues are formed. A power quality crisis refers to the problems that are cause by the increase of a non standard voltage or current or frequency.

Dynamic Voltage Restorer(DVR) with a Z-Source AC Converter Topology
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2010This paper proposes a new type of voltage sag-swell compensator based on a Z-source AC-AC converter. The proposed topology employs a pulse width modulation (PWM) Z-source AC-AC converter along with a injection transformer. A safe commutation strategy is used to eliminate voltage spikes on switches without snubber circuit. During a voltage sag or swell,
