Antenna Tracking System: Having acquired a target through a scanning method as just described, it may then be necessary to locate it very accurately, perhaps in order to bring weapons to bear upon it. Having…
Stator Protection: Stator Protection - The type of stator faults likely to occur have been discussed already. The earth-fault current is usually limited by resistance in the neutral of the generator. Depending upon the amount…
Performance of Three Phase Short Transmission Line: For reasons associated with economy, transmission of electric power is done by Three Phase Short Transmission Line. This system may be regarded as consisting of three single Phase…
Mechanical Principles in Transmission Lines: Mechanical Principles in Transmission Lines design should depend to some extent on the importance of continuity of operation in the line under consideration. In general, the strength of the line should…
Reverse Bias PN Junction: When an external bias voltage is applied to a pn-junction, positive to the n-side and negative to the pride, electrons from the n-side are attracted to the positive terminal, and holes…
Digital Satellite Communication - Definition and Advantages: With the developments in digital electronics technology, access techniques and possibility of expanded communication network, digital signaling techniques have been introduced in communication by the satellite. Some of…
Display Methods in Radar System: The output of a radar receiver may be displayed in any of a number of ways, the following three being the most common Display Methods in Radar System are: Deflection…
Load Commutated Chopper Circuit: In this method of Load Commutated Chopper Circuit, the load current flowing through the thyristor is made to become zero while the motor current is conducted by the free-wheeling diode. Figure…
Voltage Multiplier Circuits: Cascaded Voltage Multiplier Circuits for higher voltages are cumbersome and require too many supply and isolating transformers. It is possible to generate very high d.c. voltages from single supply transformers by extending…
Recent Trends in Power Semiconductors: The recent trends in Power Semiconductors from application point of view show that MOSFETs and IGBTs are replacing BJTs almost completely while GTOs are currently being used for high V…
