Generation of Switching Surges: Nowadays in extra high voltage transmission lines and power systems, switching surges is an important factor that affects the design of insulation. All transmission lines rated…
Generation of High Frequency AC High Voltage: High Frequency AC High Voltage are required for rectifier d.c power supplies. Also, for testing electrical apparatus for switching surges, High Frequency AC…
Electrostatic Generators: Van de Graaff generators are essentially high voltage but low power devices, and their power rating seldom exceeds few tens of kilowatts. As such Electrostatic Generators machine which…
Field Oriented Control of Three Phase Induction Motor: The stator current of an induction motor has the functions of producing the required air gap flux (magnetisation) as well as developing…
Function Generation and Linearisation: An important aspect of the closed loop control system is the use of Function Generation and Linearisation, e.g. in the control of induction motors there exists…
Feedback Control in Drive System: Feedback Control in Drive System - A closed loop control of a variable speed drive system employing thyristor power converters is normally a discrete time…
Gate Firing Converters: The firing pulse control unit constitutes the heart of any thyristor power conÂverter. The Gate Firing Converters required by the thyristors are often derived from the digital…
Control System Performance: From the foregoing discussion on control systems it can be seen that the beÂhaviour of the control systems can be specified, based on several time domain specifications.…
