In grid-connected power generation systems, dc-link voltage control is needed to prevent energy losses, reduce fluctuations and provide a stable flow. addition, of the factor via source inverter process that supports efficient use produced. Moreover, keeping total harmonic distortion (THD) current injected into grid in accordance with IEEE-519 standards (

Abstract Injected electrons and holes are captured into quantum wells with a non-vanishing time. Simulation results presented, showing that this in non-equilibrium of free bound carriers diode laser. Analysis an exemplary laser structure is used to show if the capture time too large, carrier densities regions adjacent well rise strongly beyond their values at threshold very high output power.

We propose and demonstrate a novel and cost-effective optical transmitter based on incoherent-light-injected reflective semiconductor optical amplifiers (RSOAs) which can be upgraded to higher data rate without discarding the existing low-data-rate transmitter. The transmitter is based on optical time-division multiplexing (OTDM) of return-to-zero modulated RSOAs and thus capable of upgrading t...

Start of fuel injection and fuel type are two important factors affecting engine performance and exhaust emissions in internal combustion engines. In the present study, a one-dimensional computational fluid dynamics solution with GT-Power software is used to simulate a six-cylinder diesel engine to study the performance and exhaust emissions with different injection timing and alternative fuels...

Techniques are presented to compactly represent substrate noise currents injected by digital networks. Using device-level simulation, every gate in a given library is modeled by means of the signal waveform it injects into the substrate, depending on its input transition scheme. For a given sequence of input vectors, the switching activity of every node in the Boolean network is computed. Assum...

Lack of adequate transmission capacity is a major impediment in connecting more of renewable energy sources (wind, solar) into the transmission grid.This paper at first presents a control algorithm for a single-phase grid-connected photovoltaic system in which aninverter designed for gridconnected photovoltaic arrays can synchronize a sinusoidal current output with a voltage grid. The power pro...

In distribution systems, sudden change in load draws non-sinusoidal currents and causes the load harmonics, excessive neutral currents creates disturbance and changes in Power factor. Static Synchronous Compensator (STATCOM) is used to provide reactive power to the transmission line. In this paper proposes with Fuzzy Logic Controller (FLC) to tune PI controller gain values under different opera...

For monoenergetic acceleration of electrons, the injected particles need to be bunched with the same periodicity as the accelerating structure. In a laser-driven plasma beatwave accelerator, the accelerating structure (plasma wave) is phase-locked to the CO2 beat-wave used to drive it. Using the same beat-wave to generate high power FIR radiation via difference frequency mixing in GaAs ensures ...
