A long-termexperiment was conducted withthe objective ofselectingthe appropriate land managementtreatments andtoidentify the key indicators of soil quality for dryland semi-arid tropical Alfisols. The experiment was conducted using a strip split–split plot design on an Alfisol (Typic Haplustalf) in southern India under sorghum (Sorghum vulgare (L))-castor(More)
High level penetration of Distribution Generation causes several impacts on distribution system. One such impact is distribution feeder protection. Modeling of distribution feeder protective devices like reclosers and sectionalizers will help in thorough understanding of the dynamic behavior of the protective system with DG. This paper discusses the(More)
This paper presents a review on recent developments in BLDC motor controllers and studies on four quadrant operation of BLDC drive along with active PFC. The main areas reviewed include Sensor-less control, Direct Torque Control (DTC), Fuzzy logic control, controller for four quadrant operation and active Power Factor Corrected (PFC) converter fed BLDC(More)
dq components of currents are extensively used in the controller applications of industrial drives as they are dc quantities. In this paper, it is shown that these components will no longer remain as dc quantities, if they are extracted from the induction motor suffering from mixed air gap eccentricity. A dynamic model of an induction motor suffering from(More)
