Research ArticleOpen accessIn the abstractA NOVEL ARTIFICIAL HYDROCARBON NETWORKS BASED SPACE VECTOR PULSE WIDTH MODULATION CONTROLLER FOR INDUCTION MOTORSHiram Ponce, Luis Ibarra, Pedro Ponce, Arturo MolinaMost of machine-operated industrial processes implement electric machinery as their work sources, implying the necessary improvement of control techniques and power electronics drivers. Many years have passed since the control conflicts related to induction motors have been overcome through torque-flux control techniques so their advantages over direct current motors have made them to be the most common electric actuator found … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 26 Feb 2014 · 7,039 accessesView PDFCite
Research ArticleOpen accessIn the abstractHARMONICS REDUCTION IN FRONT END RECTIFER OF UNINTERRUPTIBLE POWER SUPPLIES WITH ACTIVE CURRENT INJECTIONT. Chandrasekar, B. Justus Rabi, A. KannanHarmonics are the by-products of modern electronics devices so it is necessary to mitigate the harmonics and offer techniques to mitigation of harmonics. It is greatly hampered by a three phase rectifier used as a front-end ac-to-dc converter in many systems. High power factor is achieved by injecting high-frequency currents into the three-phase rectifier. This study presents the high power … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 1 Feb 2014 · 6,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractArtificial Neural Network Controller Based Distribution Static Compensator for Voltage Sag MitigationD. Rajasekaran, Subhransu Sekhar Dash, Arun Bhaskar Mayilvaganan et al.Switching of loads, capacitors, along with the proliferation of power electronics equipment, non-linear loads in industrial, commercial and domestic applications have lead to power quality issues in the distribution system. Power quality issues such as voltage sag, voltage swell and harmonics, which are certainly major concerning issues in the present era. These issues can lead to failure or malfunction of … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 21 Jun 2013 · 6,955 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Based Plus Integral Controller for PMBLDC Motor Control using Resonant Pole InverterMuruganantham, PalaniPermanent Magnet Brushless DC (PMBLDC) motor drives are increasingly popular in industrial applications due to rapid progress of technologies in power electronics and the growing demand for energy saving. The increasing demand of energy saving from society is the external force for the development of PMBLDC motor drives.
