Transient stability in Electrical Drives: Transient stability in Electrical Drives - From the preceding discussion it is clear that a drive is in its state of equiÂlibrium at constant speed if the developed motor torque…
Transistor Chopper Circuit: Transistor Chopper Circuit - A single transistor used as a dynamic switch to convert low level dc signal to an ac waveform is shown in Fig. 14.34. If the voltage applied to…
Inverse Transformation: We already discussed Laplace transforms of a functions f(t). If the function in frequency domain F(s) is given, the Inverse Transformation can be determined by taking the partial fraction expansion which will be…
Phase Margin Optimum: The method can be based on the phase margin in which the controller is designed to provide a minimum phase margin. The design makes use of Bode plots. The ratio of time…
Common Emitter Amplifier Circuit: Consider the Common Emitter Amplifier Circuit circuit shown in Fig. 6-17. When the capacitors are regarded as ac short-circuits, it is seen that the circuit input terminals are the transistor base…
Static Relays Basics and Classification: A Static Relays Basics refers to a relay in which the measurement or comparison of electrical quantities is done in a static network which is designed to give an output…
Fixed Positive Voltage Regulators: The series 7800 regulators provide eight voltage options, rangÂing from 5 to 24 V, as indicated in Table 43.2. These ICs are designed as fixed voltage regulators and with adequate heat…
Telemetry in Electronic Communications: Telemetry in Electronic Communications consists of performing measurements on distant objects. Although hydraulic or wire circuits may be used for this purpose, this section will deal with radiotelemetry only, particularly as…
2 Pole Elementary DC Machine: Figure 5.13 shows a 2 Pole Elementary DC Machine with a single coil rotating armature. It may be seen that the field winding is stationary with salient poles whose pole-shoes…
Difference between FIR Filter and IIR Filter: The difference between FIR Filter and IIR Filter is given in table below Sl no Bilinear Transformation Impulse Invariant Method 1 These filters can be easily designed to…
