A need to reduce the harmonics and reactive power in the system has occurred mostly due to large use of power electronic apparatus. The comparison of the technologies developed for handling harmonic and reactive power ...

Low voltage high current rectifiers are required for many industrial applications. Traditionally, these rectifiers have been manufactured by using simple diode bridge rectifiers fed through auto-transformer and transformer ...

The conventional converters have inherent drawbacks. like high current harmonics, low power factor and non-sinusoidal line currents. To improve the power factor and reduce the current harmonics, several circuit topologies ...

In this thesis work, first the dynamic modeling of the induction motor has been described because per-phase equivalent circuit analysis it is not appropriate to predict dynamic performance of the motor. In order to understand ...

In the present work the performance of induction motor in traction system, which is fed by voltage source inverter, is investigated. The inverter is operated in space vector mode to make input and output current sinusoidal. ...

The switched reluctance motor (SRM) drive is receiving increasing attention from various researchers as well as industry as a viable candidate for adjustable speed and servo applications. The switched reluctance motor is ...

One important threat of heavily loaded line is voltage instability. A prior knowledge of the voltage stability limit at various operating conditions is essential to operate the system with an adequate safety margin. With ...

Investigation of harmonics on power distribution system is presented, i.e. qualitative overview study of the distribution power system with the goal of understanding harmonics waveform distortion within it, and to provide ...

A majority of railway traction drives in use today still utilize DC motors. The most appreciated DC motor for traction purpose is DC series motor because of its inherent high starting torque capacity. In early days most ...

Power system engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. Flexible AC Transmission system (FACTs) controllers can balance the power flow and thereby ...
