High-gain organic transistors are the key building blocks for the development of high-performance organic electronics, including high-sensitivity sensors, signal amplification in sensing systems and large-scale circuits. In this work, we analyze organic transistors based on the diffusion-driven charge-accumulation architecture. This class of organic field-effect transistors maximizes at the same the...
In this paper a non-linear second order circuit model of high temperature Sodium-Nickel Chloride batteries (SNBs) is presented. The aim is the development of an accurate model easily implementable in microgrids Energy Management System and suitable for their real-time control. The proposed model is based on the analysis of the experimental performance of a commercial 23.5 kWh SNB. In particular, the...
Electrical arcs are of great concern for power electronic systems. Modeling of arc faults to represent and predict arc characteristics and transient responses within the power system is now receiving considerable research attention. In this paper, a series DC arc fault demonstration rig is designed to generate series arcs by moving one electrode away from a stationary one with a stepper motor. Experimental...
A compact model and simulation methodology for chalcogenide based memristor devices is proposed. From a microprocessor design view point, it is important to be able to simulate large numbers of devices within the integrated circuit architecture in order to speed up reliably the development process. Ideally, device models would accurately describe the characteristic device behavior and would be represented...
The Electric Arc Furnaces is time varied and non linear load that up to now so many models are suggested for the analysis of its operation. This kind of unstable load can make many problems in power quality (i.e. Flicker, Sag and Swell), unstable voltage and current and harmonics for the power transmission network. In this essay, you can find a new model for making a model for the Electric Arc Furnaces...
An electrical resistance tomography sensor consists of a set of measurement electrodes. In general, finite element method (FEM) is used to solve the forward problem (i.e. calculate the resistance value for a given conductivity distribution and electrodes setup). In this paper, a new approach is proposed. The equivalent resistor network model of an electrical resistance tomography (ERT) sensor has...
This paper deals with the fractional order modelling of the supercapacitor voltage response for a given current profile. The model is obtained using the porous electrode theory applied on the supercapacitor case. In order to simplify the complexity of the model, it is assumed that there is no diffusion process in the electrolyte. These assumption leads to neglect the supercapacitor self-discharge...
The main goal of this paper is to establish a link between the ultracapacitors impedance at low frequency and slow phenomena such as self-discharge and charge recovery. Usually these phenomena are studied in the time domain. However, additional information can be extracted from specific characterization methods in the frequency domain like impedance spectroscopy. In this way, we intend to introduce...
