The majority of work carried out around battery models is partly motivated by vehicle simulation. Specifically for electric vehicle simulation, some characteristics of the battery require more attention while others can be simplified, thus distinguishing dynamic models for battery system simulation slightly and requiring different tools. In this paper, we propose a dynamic battery model that accounts...
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...
Recently, metallic source and drain is widely discussed with LSIs scaling trend. For this technology, it is essential to fabricate low resistive Ohmic contact between electrodes and the channel materials. However, it is expected that precise Schottky barrier height control for obtaining Ohmic contact is technologically difficult. One of the main reasons is that Fermi level pinning phenomena takes...
This paper presents a low cost, easy to use digital simulator for a proton exchange membrane fuel-cell (PEMFC) stack by means of a power source controlled by LabVIEW. The simulator easily allows to implement different models and simultaneously permits to study different FC types. The FC stack is represented with a circuital model that considers the capacitive effects of the electrodes and the internal...
Graphene is a possible candidate for advanced channel materials in future field effect transistors. This presentation gives a brief overview about recent experimental results in the field of graphene transistors for future electronic applications.
Advances in micromachining technology can facilitate the integration of SAW (Surface Acoustic Wave) devices and CMOS circuitry on IC scale substrate for Monolithic fabrication. The optimal design and performance of these filters can be reached by using new Smart materials. The key component in the structure of the SAW device is the piezoelectric materials used which depends mainly on some important...
A physical yet analytical phase change memory (PCM) model simultaneously accounting for thermal and electrical conductivities is presented. Due to the physics based nature of the model, the essential temperature from heating and cooling of PCM during operation is instantaneously updated. More importantly, the model can be applied to non-conventional circuit design technique. We show that for the first...
