Dynamic voltage restorer (DVR) is a protecting device for sensitive loads which compensates grid fluctuations. Although using fault current limiting devices (FCL) method of and electrical networks against short circuits. In recent years, some methods have been proposed to combine these two reduce the cost converters use benefits each simultaneously. A new topology control DVR an FCL presented i...

Direct Volume Rendering (DVR) is a visualization technique that has proved to be a very powerful tool in many scientific visualization applications. Diagnostic medical imaging is one such domain where DVR provides unprecedented possibilities for analysis of complex cases and highly efficient workflow. Due to limitations in conventional DVR methods and tools the full potential of DVR in the clin...

Patterning of the chick telencephalon has been debated, especially in regard to a ventral (subpallial) or dorsal (pallial) nature of the dorsal ventricular ridge (DVR). Here we report the expression patterns of chick homologues of molecules known to be involved in telencephalic patterning in other vertebrate species. We show here that the transcription factors Ngn1, Ngn2, Cash1, Gsh2 and the se...

In this paper a Dynamic Voltage Restorer (DVR) is used for power quality improvement on transmission side for the voltage regulation, grid stabilization and efficient utilization. The DVR normally installed between the source voltage and critical or sensitive load. The vital role of DVR depends on the efficiency of the control technique involved in switching circuit of the inverter. The DVR is ...

Dynamic Voltage Restorer (DVR) is used in power distribution system to protect sensitive loads in voltage disturbances. The performance of DVR is related to the adopted configuration and control strategy used for inverters. In this paper, an asymmetrical voltage-source inverter controlled with fuzzy logic method based on hysteresis controller, is used to improve operation of DVR to compensate v...
