Voltage Regulation of Synchronous Generator: The Voltage Regulation of Synchronous Generator is defined on lines similar to that of a transformer. Consider the generator supplying full-load current at a specified power factor and rated terminal…
Voltage Regulation Formula of Transformer: Voltage Regulation Formula - Constant voltage is the requirement of most domestic, commercial and industrial loads. It is, therefore, necessary that the output voltage of a transformer must stay within…
Voltage Commutated Chopper Circuit: This Voltage Commutated Chopper Circuit comprises an auxiliary thyristor Th2, a diode D, inductor L and capacitor C as shown in Fig. 11.32 wherein the total chopper circuitry has been outlined…
Voltage and Harmonic Control of Inverters: Voltage and Harmonic Control of Inverters - In applying Inverters for motor control both V and f (keeping V/f constant) need to be varied. Further, the inverters apply essentially…
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 excited dc motor in industry.…
Variable Reluctance Stepper Motor Working Principle: A Variable Reluctance Stepper Motor Working Principle consists of a single or several stacks of stators and rotors-stators have a common frame and rotors have a common shaft as…
Variable Frequency Transformer | Application: So far we have considered transformers which operate at fixed frequency (50 Hz). Their purpose is to transform electric power from one voltage level to another; their performance measures being…
Types of Single Phase Synchronous Motor: There are two types of single phase synchronous motor, namely, Reluctance Motor Hysteresis Motor Construction of Reluctance Motor and Torque Speed Characteristics: The reluctance motor, in general, results wherever…
Types of Rotating Electric Machine: The Types of Rotating Electric Machine are namely the dc machine, the polyphase synchronous machine (ac), and the polyphase induction machine (ac). Three materials are mainly used in machine manufacture;…
Types of Magnetic Leakage Flux in Induction Motor: The Magnetic Leakage Flux in Induction Motor is that flux which links only the stator or only the rotor windings. Because of the presence of air-gap in…
