Harmonic Equivalent Circuit of Induction Motor: When fed from an inverter or cycloconverter, the motor terminal voltage is non-sinusoidal but it has half-wave symmetry. A non-sinusoidal waveform can be resolved…
Closed Loop Speed Control of DC Motor: Closed Loop Speed Control of DC Motor - The converters (rectifiers and choppers) are built using semiconductor devices, which have very low thermal…
Single Phase Fully Controlled Rectifier Control of DC Motor: The Single Phase Fully Controlled Rectifier Control of DC Motor is shown in Fig. 5.26(a). Motor is shown by its equivalent…
Phase Locked Loop Control(PLL): A PI controller ideally should provide perfect speed regulation. However, due to imperfections in sensing and control circuits, the closed-loop schemes described earlier can at best…
Current Sensing of Electrical Drives: Current Sensing of Electrical Drives is required for the implementation of current limit control, inner current control loop of closed-loop speed control, closed-loop torque control…
Current Limit Control of Drives: Current Limit Control of Drives scheme of Fig. 3.3 is employed to limit the converter and motor current below a safe limit during transient operations.…
Fiber Optic Components and Systems: The Fiber Optic Components and Systems can be divided into subgroups, the source, the link, and the detectors. We will now explore the makeup and…
Color Television Receiver Block Diagram: Figure 17-25 shows the block diagram of a Color Television Receiver Block Diagram, but for simplicity the circuits shown in Figure 17-23 are omitted. Interconnection…
