Permanent Capacitor Single Phase Induction Motor: Permanent capacitor single phase induction motor, also sometimes called the single-value capacitor—run motor, has two stator windings placed mutually 90 electrical deÂgrees apart. The main or running winding is…
Voltage Doubler Circuits: Both full wave and half wave rectifier circuits produce a d.c. voltage less than the a.c. maximum voltage. When higher d.c voltages are needed, a Voltage Doubler Circuits or cascaded rectifier doubler…
Series Inductance in Impulse Generator Circuit: Often Series Inductance in Impulse Generator Circuit are required to test equipment with large inductance, such as power transformers and reactors. Usually, generating the impulse voltage wave of proper…
Three Phase Drives: Single phase drives discussed in the previous section are employed for low and medium powers. When the power of the drive is very large the three-phase converter is preferred for supplying the…
Speed Control of Induction Motor: Stepless control of speed of induction motors cannot be carried out as efficiently and inexpensively as for dc motors. Various methods of Speed Control of Induction Motor can be visualized…
Single Phase Bridge Inverter: A serious disadvantage of the half-Bridge Inverter of Fig. 11.46 is that it requires a 3-wire dc supply. This is overcome by the commonly employed Single Phase Bridge Inverter circuit of Fig.…
RF Signal Generator: An RF signal generator, when used for alignment and testing of the RF and IF stages of a TV receiver, permits recording of circuit performance at one frequency at a time. Therefore,…
What is Clipper Circuit? - Definition and Classification Clipper Circuit is one which controls the shape of the waveform by removing or "clipping" off an unwanted portion. A half-wave rectifier is an example of the…
JFET Characteristics: An n-channel JFET Characteristics block representation is shown in Fig. 9-6. With a drain-source voltage applied as illustrated, ID flows in the direction shown producing voltage drops along the channel. Consider the voltage…
Speed Governor Dead Band and its Effect on AGC: The effect of the Speed Governor Dead Band is that for a given position of the governor control valves, an increase/decrease in speed can occur before…
