Ward Leonard Method of Speed Control: Known after the name of its inventor Ward Leonard Method of Speed Control (1891), it consists of a separately excited generator feeding the dc…
Dynamics of Electrical Drives Articles: Torque Equation of Motor Load System: A motor generally drives a load (machine) through some transmission system. While motor always rotates, the load may rotate…
Ruby Maser: As was know ferrites of certain materials have atomic systems that can be made to resonate magnetically at frequencies dependent on the atomic structure of the material and…
Gunn Diode Working Principle: A practical Gunn Diode Working Principle consists of a slice like the one shown in Figure 12-24, sometimes with a buffer layer between the active layer…
Tunnel Diode Applications: In all its Tunnel Diode Applications, the tunnel diode should be loosely coupled to its tuned circuit. With lumped components, this is done by means of a…
Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
Radio Receivers Articles: Tuned Radio Frequency Receiver: The Tuned Radio Frequency Receiver is a simple “logical” receiver. A person with just a little knowledge of communications would probably expect all…
Receiver Types: There are Two Receiver Types namely, Pilot Carrier Receiver and a Suppressed Carrier Receiver; the suppressed carrier receiver incorporates a frequency synthesizer for extra stability and also is…
