Control of Electric Motor Articles: Control of DC Electric Motor: A separately excited DC Electric Motor is very versatile as a variable speed motor. Its speed can be varied by…
Current Source Inverter Fed Induction Motor Drive: Current Source Inverter Fed Induction Motor Drive - In a voltage source inverter fed induction motor the applied voltage to the stator is…
Static Scherbius Drive: The main limitation of the Kraemer drive discussed is the operation at sub-synchronous range due to diode rectifier. Super synchronous speeds can be achieved if the power…
Four Quadrants Converters: Four Quadrants Converters - The converters described in the previous sections are suitable either for one quadrant or two quadrant operation. In the former case stepless speed…
Three pulse midpoint converter: These are basically three-phase converters, and are very popular because a 3-phase supply is readily available. 3-phase converters have a greater power capability than single phase…
Switching Transistor: The characteristics of modern Switching Transistor are specially suited to the functional requirements mentioned already. These along with the other Semiconductor production of static relays. The properties particularly…
Timer: Timer is an instruction that waits a set amount of time before doing something. The different kinds of timers are available with different manufacturers. Most of the timers are:…
Analog Electronics Process Controllers: An Analog Electronics Process Controllers must be capable of providing one or more of the three main methods of control, namely, Proportional, Integral and Derivative. The…
