The purpose of this paper is to show the working limits of a Variable Speed Wind Turbine. The system is based on a Doubly-Fed Induction Generator and a Fixed-Pitch Wind Turbine. The machine rotor is connected to the network through an AC/AC Converter in order to allow energy recovery. Thermal, mechanical and electric limits are investigated. The study of the machine is based on a steady state m...

Railway traction is a more stochastic heavy load connected system. Due to the usage of ac-dc converters and ac-ac converters, the various power quality issues become the major problems in the electric system. This paper presents a review on power quality conditioners suitable for Railway traction based on the configuration, components involved and on the technical and economic considerations. M...

The Department of Clinical Physiology, Nuclear Medicine and PET, Rigshospitalet, Denmark The Dixon-Water-Fat segmentation (DWFS) method is a standard attenuation correction (AC) method in PET/MRI on the Siemens mMR and has demonstrated a systematic quantitative bias in [18F]-FDG-PET/MRI studies of the brain compared to PET/CT. The aim of this study was to evaluate the impact of DWFS-AC in a hyb...

The presented paper deals with the implementation of the Switching Table Based Direct Torque Control (ST-DTC) in the matrix converter-fed induction motor drive. In order to improve the control of the matrix converter input power factor, the use of the simplified Indirect Space Vector Modulation (ISVM) was proposed. To verify the feasibility of the proposed solution, experimental results were pr...

This paper presents a new method to compensate the nonlinearity for matrix converter drives using disturbance observer. The nonlinearity of matrix converter drives such as commutation delay, turn-on and turn-off time of switching device, and on-state switching device voltage drop is modeled by disturbance observer and compensated. The proposed method does not need any additional hardware and of...

In this study, a switch-mode three-phase active tracking AC-AC voltage regulator based on the boost converter is proposed with moderate number of and passive elements used in topology. A robust hybrid control, where novel designed feedforward controller supports closed-loop PID controller, for control apart from similar studies literature. Active response reference output phase voltages augment...

BACKGROUND Development of theranostic concepts that include inductively coupled plasma mass spectrometry (ICP-MS) and laser ablation ICP-MS (LA-ICP-MS) imaging can be hindered by the lack of a direct comparison to more standardly used methods for in vitro and in vivo evaluation; e.g. fluorescence or nuclear medicine. In this study a bimodal (or rather, hybrid) tracer that contains both a fluore...

Electrical power grids are rapidly evolving into smart grids, with homes also making an important contribution to this. In fact, the well-known and emerging technologies of renewables, energy storage systems electric mobility each time more distributed throughout grid included in homes. such circumstances, since these natively operating DC, it is predictable for a revolution electrical craving ...

Based on focused ion beam and shear friction apparatus data, the multi-resolutions (0.2 nm–5 μm) volume roughness & asperity contact (VR & AC) three-dimensional structure on principle slip surface interface-surface (PSS-IS) is measured on high performance computational platform; and physical plastic-creep friction model is established by using hybrid hyper-singular integral equation & lattice B...

This paper presents a smart DC micro-grid system for plug-in electric vehicle charging and discharging. This DC microgrid integrates the plug-in battery electric vehicles (BEVs) & plug-in hybrid electric vehicles (HEVs) together with the AC supply module, storage energy module, and intelligent control module. By connecting with the AC power source and the storage energy module, this grid can of...
