Electric circuit analysis determines the voltage and current distribution in an electric circuit due to applied source voltages or currents. In a static (DC) electric circuit analysis, the voltage and current distribution in an electric circuit is determined that is subjected to applied DC source voltages or currents. In a harmonic (AC) electric circuit analysis, the voltage and current distrib...

We report the effect of confinement on the electric field induced orientation of a nematic liquid crystal, 4-cyano-4'-hexylbiphenyl (6CB), between mica surfaces. The resonance shear measurement was employed for monitoring changes in the viscosity of 6CB at various surface separation distances (D) with and without an applied electric field. The viscosity depended on the surface separations, and ...

For many industrial applications that including electric motor, selecting of the appropriate motor type is keypoint for the application success and efficiency. This paper presents a comparative performance evaluation between direct torque controlled Brushless AC and Brushless DC motors which have been considered as traction motor on electric vehicles. Moreover, a short review to brushless AC an...

The helical pitch as a function of low-frequency ac electric field at different temperatures has been investigated in a ferroelectric liquid crystal both experimentally and theoretically. A simplified model has been presented to calculate the variation of helical pitch under such fields, and the results obtained are in good agreement with the experiment. The frequency dispersion oftbe pitch has...

In this paper, an electric vehicle drive with a robust and low cost alternating current (AC) induction motor is presented. This approach is applied to an existing commercial utility electric vehicle where previously used direct current (DC) series motor was replaced by the new AC induction motor. The use of three-phase squirrel cage induction motor requires implementing of voltage source invert...

Abstract Electrostatic induction charge which generated by the coupling effect of hybrid electric field AC/DC cross line and metal object under transmission can cause different levels shock injury to human. In order find out distribution law reduce electrostatic induction, this paper set up shielding lines paralleled AC DC respectively on outside side conductors along diagonal parallelogram at ...

The monitoring of overhead power line networks is becoming increasingly more challenging because of the power distribution of renewable energy resources. The use of ambient energy is important for a maintenance free supply of a wireless monitoring network. Generally, the electromagnetic field resulting from the AC current and the electrostatic field resulting from the AC voltage can be used. Ne...
