Phasor Diagram of Synchronous Motor: The Phasor Diagram of Synchronous Motor is the most important element of a power system. It converts mechanical power into electrical form and feeds it…
Flux Linkages of an Isolated Current Carrying Conductor: Transmission lines are composed of parallel conductors which, for all practical purposes, can be considered as infinitely long. Let us first develop…
Vector Control of Induction Motor: The sole idea behind the vector control of induction motor is to have an electrical drive which must offer superior performance than widely used separately…
Types of Forced Commutation: It was observed from the discussion on choppers and inverters that in thyristor systems fed from dc supply, the forward current does not pass through zero…
Gate Turn Off Thyristor (GTO) - Symbol, Operations and Applications: Conventional thyristors are used as ideal switches in power electronic applications. They have the capability of blocking several thousand volts…
Four Phase Stepper Motor: Four Phase Stepper Motor - The stepper motor is a special type of synchronous motor which is designed to rotate through a specific angle (called a…
Ion Implantation Process in IC Fabrication: As we know, the conductivity of the semiconductor increases when small impurity is added to it. The process of adding impurity is called doping…
Brushless DC Motor: The term Brushless DC Motor is applied to many configurations of ac synchronous motors in which semiconductor control is used to control stator currents such that maximum…
