Research ArticleOpen accessIn the keywordsEffects of Low Frequencies on Three Phase Induction Motor Performance Operating in Close Proximity to Rated SpeedQazem Jaber, Qais Naman, Mahdi ShamaseenVariable speed drives (VSD) are adhered to induction motors in most of the present industrial applications. And since the world has become more conscientious to energy saving, inverters established them selves in domestic buildings and industry. Square wave inverters generate dominant harmonics of the 5th, 7th, 11th and 13th order. Inverters based on PWM strategy produce much higher harmonic order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRobust and Efficient Controller to Design a Standalone Source Supplied DC and AC Load Powered by Photovoltaic GeneratorHassan AbouobaidaThe present work describes the analysis, modeling and control of a cascade DC-DC and DC-AC power conditioning stage to control a output voltage to supply a DC and AC load systems. To maximize energy extracted from PV generator and control output voltage a RCC MPPT and backstepping controller are designed. The stability of the control algorithm is demonstrated by means … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 26 Oct 2016 · 7,723 accessesView PDFCite
