A power VDMOSFET has been simulated using PISCES-II, a 2-D numerical device simulator. The doping densities and device dimensions are chosen so as to simulate a typical device structure with one micron channel length. These simulations are aimed at understanding the device physics through various internal electrical quantities like potential distribution, electric field distribution, and electr...

An interpretation of high-frequency (20–2400 Hz) fast quasiperiodic oscillations of magnetars in terms of an equivalent electric circuit is given. Observed periods and the very high quality of quasi-periodic oscillations are explained. The oscillation source is represented as a hot electron-positron plasma in a ‘trapped fireball’, a system of current-carrying magnetic loops of various sizes. Th...

The lithium-ion battery is a complex system that both non-linear and non-stationary, which involves electrical, thermal electrochemical dynamics In order to deepen the understanding of dynamics, in this paper, an electro-thermal coupled model proposed for 40 Ah cell with Nickel Manganese Cobalt Oxide cathode material graphitic anode. developed takes into account high power applications then all...

The paper outlines a method for inclusion of the impact of eddy-currents in the model for dynamic prediction of current waveform and force of a switched reluctance machine. The method is based on the equivalent electric circuit model which accounts for the impacts of magnetic saturation and eddy currents in the magnetic core. A linear tubular switched reluctance machine, which includes solid st...

A series of polymer dispersed liquid crystal devices using glass substrates have been fabricated and investigated focusing on their electrical properties. The devices have been studied in terms of impedance as a function of frequency. An electric equivalent circuit has been proposed, including the influence of the temperature on the elements into it. In addition, a relevant effect of temperatur...
