A simple and economical power conditioner to convert the power available from solar panels into 60 Hz ac voltage is described. The raw dc voltage from the solar panels is converted to a regulated dc voltage using a boost converter and a large capacitor and the dc output is then converted to 60 Hz ac using a bridge inverter. The ratio between the load current and the short-circuit current of a P...

An isolated small wind turbine emulator based on a separately excited DC motor is developed to evaluate the performance of small wind turbine control strategies. The test rig consists of a 3HP separately excited DC motor coupled to a synchronous generator. A dump load is connected to the generator through a buck-boost converter controlled by a microcontroller. Wind turbine rotor and furling dyn...

A maximum dynamic ow generalizes the standard maximum ow problem by introducing time. The object is to send as much ow from source to sink in T time units as possible. A related problem is the universally maximum ow, which asks to send a ow from source to sink that maximizes the amount of ow arriving at the sink by time t for all t T. We consider a further generalization of this problem that al...

A renewable energy source plays an important role in electricity generation. Various renewable energy sources like wind, solar, geothermal, ocean thermal, and biomass can be used for generation of electricity and for meeting our daily energy needs. Energy from the sun is the best option for electricity generation as it is available everywhere and is free to harness. On an average the sunshine h...

In this paper we derive a Newton scoring algorithm for the maximum likelihood separation and directionof-arrival estimation of constant modulus (CM) signals, using a sensors array. We present a rapidly converging scheme for the joint estimation of the signals and their directions, based on their CM property. We discuss initialization and show that the complexity is moderate. 2

We present a new class of perceptron-like algorithms with margin in which the “effective” learning rate, defined as the ratio of the learning rate to the length of the weight vector, remains constant. We prove that the new algorithms converge in a finite number of steps and show that there exists a limit of the parameters involved in which convergence leads to classification with maximum margin.

Solar energy availability and high installation costs of photovoltaic system encourage to extract maximum power from solar radiation. Since conventional methods cannot differentiate change in power due to perturb voltage and changing weather condition, these algorithms are prone to change under varying climatic conditions. The proposed system presents the high efficiency maximum power point tra...

The Intel® CoreTM i7 processor code named Nehalem has a novel feature called Turbo Boost which dynamically varies the frequencies of the processor’s cores. The frequency of a core is determined by core temperature, the number of active cores, the estimated power and the estimated current consumption. We perform an extensive analysis of the Turbo Boost technology to characterize its behavior in ...
