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 · 6,807 accessesView PDFCite
