A new current pulsewidth modulation (PWM) method is presented which uses the principle of creating zero three-phase currents at selected instants of time, through which the load current harmonic content can be controlled along with the magnitude of its fundamental content. This gives rise to reduction of motor torque ripples through the selection of(More)
A new three-phase current source inverter topology is presented, consisting of three single-phase bridge inverters connected in series and feeding the isolated windings of a standard three-phase induction motor. Because a current zero in one phase now does not affect the others, it enables the implementation of a wide range of current PWM patterns for the(More)
Wireless power transmission systems has revolutionized the transmission of power in various application. The concept has gained momentum recently. This work presents an exhaustive insight and detailed discussion on the components of a systems having Wireless Power Transfer (WPT) and the various techniques used for its implementation. The use of WPT in(More)
This paper presents the effectiveness of a microgrid (MG) in a distribution system. The combined heat and power (CHP) system is used to enhance the overall efficiency of the power system. Microturbines are used for CHP operation in this paper. The various methods of control of the MG are discussed. A simple low-cost model is proposed for MG based on(More)
Renewable energy potential in the form of wind or micro hydro are available in abundance at rural locations far away from city habitat. To harness this green energy the rugged induction generator has come up as a viable option. However, induction generator has change in reactive power requirement with change in load. This dynamic reactive power requirement(More)
Diode and thyristor based solid state converters are preferred because of their high reliability in applications for bulk power conversion. These converters generally use Power diodes or SCR (silicon controlled rectifiers) which has non-linear characteristics. Due to this reason such converters generate highly non-sinusoidal currents at the power supply(More)
The FAO AquaCrop model has been widely applied throughout the world to simulate crop responses to deficit water applications. However, its application to saline conditions is not yet reported, though saline soils are common in coastal areas. In this study, we parameterized and tested AquaCrop to simulate rice yield under different salinity regimes. The data(More)
