A sub-synchronous oscillation (SSO) suppression strategy of attaching virtual resistance controllers to the rotor-side converter (RSC) doubly-fed induction generator (DFIG) is proposed in this study suppress caused by series compensation and grid connection DFIG. DFIG-based frequency domain impedance model considering RSC control under small signal perturbations developed a three-phase stationa...

Lequation de magneto transport relative aux porteurs minoritaires charge dans la base photopile au silicium a jonctions verticales series, est resolue, munie des conditions limites, definies par les vitesses recombinaison jonction et en face arriere. Le photocourant phototension sont determines, representes caracteristique courant-tension (Iph(Sf)-Vph(Sf)) sous eclairement monochromatique. mode...

As solar energy costs continue to drop, the number of large-scale deployment projects increases, and the need for different analysis models for photovoltaic (PV) modules in both academia and industry rises. This paper proposes a modified equivalent-circuit model for PV modules. A PV module comprises several series-connected PV cells, to generate more electrical power, where each PV cell has an ...

A breast tissue-equivalent series (BRTES) of phantoms is manufactured to mimic both the attenuation and the density of the range of glandular and adipose tissue compositions encountered in mammography. The BRTES simulates breast tissues across the range of 20% to 70% glandularity and can be assembled in a variety of thicknesses to represent a compressed breast thickness corresponding to glandul...

With ever growing concerns on energy crisis and environmental issues, alternative clean and energy efficient vehicles are favoured for public applications. Internal combustion engine(ICE)-powered series hybrid buses and fuel cell (FC) hybrid buses, respectively as a near-term and long-term strategy, have a very promising application prospect. The series hybrid vehicle utilizes an ICE/FC as the ...

The objective of this paper is to study the effect of the internal transducer resistance on the dynamic behaviour and the output power of an energy harvester when it is attached to a cubic load resistance. It is seen that by considering the internal resistance, the dynamic equation of a conventional nonlinear energy harvester changes so that it is not easy to separate the linear damping from th...

This paper presents an analysis of LCR second-order low-pass filter capacitor to achieve a specified ripple output voltage in Buck, forward, Zeta, and Ćuk PWM DC-DC power converters for continuous-conduction mode (CCM). Current waveforms across components are derived. Using the waveform ac component voltage, expression is developed terms capacitance equivalent series resistance. The results can...

This article proposes a method for reducing the loading effects when DC voltage or current is measured in linear circuit with digital multimeter (DMM). In proposed method, voltmeter placed series to estimate current, and ammeter parallel voltage, which opposite of conventional approach. Its application particularly interest equivalent resistance between nodes (current) under measurement high (l...
