The air-cored resonant induction machine removes the magnetic core, so fields produced by windings are truly 3-D in nature. end-windings normally regarded as a nonactive and leakage source conventional iron-cored machines now become an active part contribute to torque production. Therefore, electromagnetic modeling can no longer be reduced 2-D analysis, inductance calculation becomes key proble...

From graphical model obtained, mathematical state space can be determined. Thus, studies electromagnetic transients analyzed. Likewise, this physical domain applied to balanced or unbalanced storage elements (inductances capacitances) connected linearly independ...

For System-on-Chip (SoC) using deep sub-micron technologies, semiglobal and global interconnects are susceptible to crosstalk defects that may lead to mal-function and timing failures. Removal of crosstalk defects is becoming important to ensure error-free operation of an SoC. To efficiently evaluate crosstalk-defect coverage, it is necessary to understand the factors affecting this noise. In t...

Previously, a dynamic model and simulation program for series wound DC motors (SWDCM) were developed in MATLAB/Simulink modelling them electric vehicles mechatronic systems. The electromagnetic characteristics of the motor (electric resistances, inductances), which serve as input parameters program, also measured. Additionally, locked rotor response measurements performed to test accuracy measu...

Abstract The screening current and its relaxation cause the variation of self- mutual inductances REBCO coils—REBCO is one high-temperature superconductors. However, most studies coil voltage analysis on a magnet, stack coils, have reported simulation results assuming invariant so far. Although conventional assumption still acceptable for fundamental analyses, it can misleading conclusions due ...

Self- and mutual inductances are major design parameters for wireless power transfer (WPT) systems. To optimize a WPT system estimate its performance in terms of received efficiency, it is essential to obtain simple, fast, accurate calculation these two parameters. The polarized double-D (DD) coils were selected due their simplicity structure, high low sensitivity misalignment conditions. This ...

A new low-leakage-inductance low-resistance design approach to low-voltage high-power isolated boost converters is presented. Very low levels of parasitic circuit inductances are achieved by optimizing transformer design and circuit lay-out. Primary side voltage clamp circuits can be eliminated by the use of power MOSFETs fully rated for repetitive avalanche. Voltage rating of primary switches ...

Abstract Analytical modeling of the PMSM often involves many simplifying assumptions. The model thus obtained is a model where the physical phenomena and dynamics are neglected during the identification of the process such that the saturation of the magnet circuit and the skin effect. However, the variation of stator resistances, cyclic inductances and moment of inertia due to the temperature a...

This paper deals with the modelling and simulation of the squirrel cage induction motor by taking into account all space harmonic components as well as the introduction of the bars skew in the calculation of the linear evolution of the magnetomotive force (MMF) between the slots extremities. The model used is based on multiple coupled circuits and the modified winding function approach (MWFA). ...
