Block Diagram of Electric Drive System: It is normal practice in control engineering to represent a control system by means of a Block Diagram of Electric Drive System, with a…
Field Oriented Control of Induction Motor: In the slip controlled drives using VSI or CSI discussed in the foregoing secÂtions, the stator voltage or stator current is controlled using slip…
Chopper Circuit with Input Inductance: The preceding discussion of the chopper assumes ideal conditions and does not consider the effects of inductances in series with the thyristors. With choppers of…
Electronic Communication Articles: This Electronic Communication Articles which includes the following topics: Principles of Communication Systems Need of Modulation in Communication System Bandwidth Requirement in Communication System External Noise in…
Surge Voltage and its Distribution and Control: The design of power apparatus particularly at high voltages is governed by their transient behavior. The transient high voltages or surge voltages originate…
Need of Modulation in Communication System: Until the process of superimposing a low-frequency (long-wave) voice information component on a high-frequency (short-wave) carrier signal was perfected, the most widely used form…
Heat Capacity of Calorimeter: Heat Capacity of Calorimeter - RF power may be directly converted into heat. Water acts as the load, and RF power may be used to heat…
Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a short ultra thin wire…
