Electromagnetic torque components in the synchronous salient‐pole machine

Dariusz Spalek

Centres on the decomposition of the total electromagnetic torque of electrical machines for two components. The proposed idea of decomposition relies on the physical meaning of…

Physical models in device simulation of SI power pin‐diodes for optimal fitting of simulation results to measured data

M. Isberg, P. Jonsson, N. Keskitalo, F. Masszi, H. Bleicher

Shows how a sensitivity analysis of different mobility models was carried out in order to reach the best fit of simulation results to measured data. Simulated data were compared…

The Child‐Langmuir asymptotics for semiconductors including phonon interactions

P. Degond, Y. Qiu

Presents a simplified mathematical model of electron transport in a one‐dimensional semiconductor device of N+ ‐ N ‐ N + type. The model is based on a singular perturbation…

Computer formulation of state space equations for systems containing electrically separate but magnetically coupled circuits

Z. Saad‐Saoud, A.C. Williamson

Presents a new approach for formulating the state space equations associated with electrical systems containing circuits which are coupled only magnetically. Presents an algorithm…

A hybrid technique for electromagnetic torque and force analysis of electric machines

T.S. Low, C. Bi, Z.J. Liu

In electric machines, the electromagnetic torques and forces are developed as a result of the interaction of the magnetic fields. These forces can be computed from the results of…
