: Induction generators are gaining the popularity due to its simplicity and no synchronization problem. However the major drawback of this machine is its additional reactive burden on the system, where it is connected. In this paper an attempt is made to explore the performance of a grid connected induction generator (GCIG) due to weak grid conditions i.e. voltage and frequency fluctuations. It...

Transient clouds cause rapid changes in the power output of Photovoltaic (PV) solar systems. These ramp rates may lead to quality problems, such as voltage fluctuations, low-voltage (LV) electricity grid. This paper firstly assesses impact a growing number distributed PV systems on profile LV grid by considering penetration 40%, 70% and 100% local rooftop capacity. Next, potential active curtai...

We present a hierarchical approach to the “atomistic” simulation of aggressively scaled sub-0.1m MOSFET’s. These devices are so small that their characteristics depend on the precise location of dopant atoms within them, not just on their average density. A full-scale three-dimensional driftdiffusion atomistic simulation approach is first described and used to verify more economical, but restri...

We present measurements of the time-dependent fluctuations of electrical current in a voltage-biased tunnel junction. We were able to simultaneously extract the first three moments of the current counting statistics. Detailed comparison of the second and the third moments reveals that the statistics is accurately described as Poissonian, expected for spontaneous current fluctuations due to elec...

Voltage noise analysis is applied to plasmalemma ion transport in Chara corallina. There is a component in the noise power spectrum that is probably associated with current fluctuations within passive transport channels, and another component that may be associated either with fluctuations in the number of open channels, or with active transport. The data allow the calculation of time constants...

Now a days in any industrial and domestic applications large power electronic equipments are increasingly used. When discussing about power electronics equipment’s having the lot of parameters are need to consider like harmonic contamination, disturbances of non-linear loads, and fluctuations of output voltages and currents etc. so in this concept the combination of shunt and TCR active filters...

We have fabricated a high mobility device, composed of a monolayer graphene flake sandwiched between two sheets of hexagonal boron nitride. Conductance fluctuations as functions of a back gate voltage and magnetic field were obtained to check for ergodicity. Non-linear dynamics concepts were used to study the nature of these fluctuations. The distribution of eigenvalues was estimated from the c...
