Combinational Circuit | Block Diagram | Design Procedure: When logic gates are connected together to produce a specified output for certain specified combinations of input variables, with no storage involved, the resulting circuit is called…
Arc Interruption Methods in Circuit Breakers: The two modes of Arc Interruption Methods in Circuit Breakers are: high resistance interruption, and low resistance or current zero interruption. High Resistance Interruption: In this case the arc…
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 in the off-state and conducting…
Emitter Follower at High Frequencies: Emitter Follower at High Frequencies circuit is given in Fig. 19.48(a). A capacitance CL is included across the load because the emitter follower is often used to drive capacitive loads.…
DC Load Line for FET: The DC Load Line for FET circuit is drawn on the device output characteristics (or drain characteristics) in exactly the same way as for a BJT circuit. Refer to the…
Two Area Load Frequency Control: Two Area Load Frequency Control - An extended power system can be divided into a number of Two Area Load Frequency Control areas interconnected by means of tie lines. Without…
Machine Tools Motors Requirements: The Machine Tools Motors Requirements are: The motors must be reliable and low cost, requiring less maintenance. They must be capable of speed control. Some applications may require operation at fixed…
Switching Systems in Digital Communication: If only two sites are to be connected, switching is not required. The two facilities are interconnected on a point-to-point basis. However, switching is likely to be required where three…
Switchgear Definition: Switchgear Definition status that, The apparatus used for switching, controlling and protecting the electrical circuits and equipment is known as switchgear. The switchgear equipment is essentially concerned with switching and interrupting currents either…
Switched Reluctance Motor: The switched reluctance motor (SRM) has both salient pole stator and rotor, like variable stepper motor, but they are designed for different applications, and therefore, with different performance requirements. A stepper motor…
