AC Excitation System - Block diagram and Working Principle: This AC Excitation system consists of an alternator and thyristor rectifier bridge directly connected to the main alternator shaft. The main exciter may either be self…
Full Wave Rectifier DC Power Supply: Like half-wave rectifiers, full-wave rectifiers require filter circuits to convert the output waveform to direct voltage. Figure 3-13 shows a Full Wave Rectifier DC Power Supply with a reservior…
What is a Digital Integrated Circuit? In an integrated circuit, components such as diodes, transistors, resistors, inductors etc. are integral parts of the chip. And on surface of this chip, which is very small piece…
Inductively Coupled Circuits: Inductively coupled multi-mesh circuits can be analysed using Kirchhoff s laws and by loop current methods. Consider Fig. 10.17, where three coils are inductively coupled. For such a system of inductors we…
Sampling Theorem Formula 1-D: One of the most important applications of digital filtering is the processing of sequences of samples derived from continuous or analog signals. This is made possible due to the results and…
Viscosity Unit: Viscosity Unit is the property of a fluid which determines the amount of resistance to a shearing stress. A real fluid has no viscosity but it is nonÂexistent. Viscosity can also be defined…
Difference Between SVC and Statcom: Difference Between SVC and Statcom may be noted that in the normal linear operating range of the V-I characteristic and functional compensation capability of the STATCOM and the SVC are…
Block Diagram of Electrical Drives | Advantages | Applications: Block Diagram of Electrical Drives - Invention of thyristor led to emergence of semiconductor drives in early sixties. The improvements in converters and development of new…
DC Motor Speed Control: In the foregoing sections we discussed the torque-speed characteristics of dc motors, bringing out the effects of armature voltage variation and field current on them. The discussion also applies to the…
Power System Stability Interview Questions and Answers: 1. Define stability limit. Ans. A stability limit is the maximum power flow possible through some particular point in the system or the part of the system to…
