In this work, we are interested in improving the performance of a doubly-fed induction generator (DFIG)-based wind system, by applying sliding mode control strategy. The objective is regulation active and reactive power, also voltage frequency signal injected into distribution network. model proposed for based on technique with estimators. was validated simulation MATLAB/Simulink.

This paper proposes an optimized step-up power converter using a quadratic sawtooth waveform generator for silicon photomultiplier (SiPM) used as radiation sensor mobile dosimeters. Although our uses the topology of switched inductor boost in voltage mode, it achieves fast transient performance thanks to proposed generator, which can increase loop bandwidth. As result, stably regulate bias SiPM...

The response of an optically injected quantum-dot semiconductor laser (SL) is studied both experimentally and theoretically. In particular, the nature of the locking boundaries is investigated, revealing features more commonly associated with Class A lasers rather than conventional Class B SLs. Experimentally, two features stand out; the first is an absence of instabilities resulting from relax...

We study the microwave absorption during electron cyclotron resonance heating (ECRH) by extraordinary wave at second harmonic (X2 mode) in T-10 tokamak and TJ-II stellarator a wide range of plasma densities, compare experiments with classical formulas for injected ECR power. Empirical relations efficiency critical density n cr , which separates regions full partial power, are obtained using num...

We report and analyze the supermode switching with current injection found for coherently-coupled dual-element vertical cavity surface emitting laser arrays. The output power, spectral characteristics, far-field mode profile are measured a range of bias operating conditions. coupling-induced enhanced power from an in-phase or out-of-phase is confirmed when approximately equal currents injected ...

This paper proposes a single phase solar based dual mode power inverter system for domestic and industrial use. Which allows the connection of additional energy sources and storage elements to a domestic photovoltaic grid connected system. The systems output port is designed to behave as a power source or sink, which allows the system to behave as power sink or source. It allows the connection ...

Electrical energy is transported from the generating point to the point of use through interconnected transmission lines .The flow of electricity through the transmission lines can be effectively and efficiently controlled by using interline power flow controllers instead of going for a new transmission lines.The construction of a new transmission lines is increasingly difficult because of vari...

To investigate the effects of repeated atropine injection on heart rate (HR) variability in resting Thoroughbred horses, two microg/ kg of atropine as parasympathetic nervous blockade was injected intravenously every 6 min to a total of 8 microg/kg after intravenous administration of 0.2 mg/kg of propranolol as sympathetic nervous blockade. We recorded electrocardiograms and obtained the HR, th...

Contrary to common belief, hollow precipitation tubes form in the absence of silicate if sodium hydroxide solution is injected into solutions of various metal ions. In many cases, the growth speed has a power law dependence on the flow rate. For vanadyl, we observe damped oscillations in the tube height.
