Research ArticleOpen accessEvery word in the titleNew Control Technique Applied in Dynamic Voltage Restorer for Voltage Sag MitigationRosli Omar, Nasrudin Abd Rahim, Marizan SulaimanThe Dynamic Voltage Restorer (DVR) was a power electronics device that was able to compensate voltage sags on critical loads dynamically. The DVR consists of VSC, injection transformers, passive filters and energy storage (lead acid battery). By injecting an appropriate voltage, the DVR restores a voltage waveform and ensures constant load voltage. There were so many types of the control … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,136 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLow Power Analog Multiplier Using MifgmosK. Duraisamy, U. RagavendranA novel 4-quadrant analog multiplier using Floating Gate MOS (FGMOS) transistors operating in saturation region are implemented. Floating gate MOSFETs are being utilized in a number of new and existing analog applications. These devices are not only useful for designing memory elements but also we can implement circuit elements. The main advantage in FGMOS is that the drain current is … …Journal of Computer Science, Vol. 9, Issue 4 · 14 May 2013 · 6,343 accessesView PDFCite
