Its a feedback control system which utilizes the saturation of the main transformer to control output voltage. It is late 1880's technology. Was used 25 years before the invention of the amplifier tube. For more information see this link: https://en.wikipedia.org/wiki/Magnetic_amplifier

What is avr in turbo generator in thermal power plant?
AVR stands for automatic voltage regulator.
What are the application of voltage shunt amplifier?
Applications of Voltage shunt feedback amplifier?
What is dropper diode voltage regulator?
The dropper diode voltage regulator is a type of voltage regulator. It is comprised of a single diode that serves as the voltage regulating device.
May power amplifier a voltage amplifier?
A power amplifier may also boost voltage; in audio equipment, power amplifiers often have a dial on the front that is used to control the input voltage gain. A simple power amplifier is composed of a single transistor; this type of configuration cannot provide voltage amplification as well. A voltage amplifier stage is needed. So the above example of an audio power amplifier is actually a voltage amplifier stage, followed by one or more power amplifier stages.
How do you troubleshoot the Automatic Voltage Regulator?
Troubleshoot the voltage regulator
What are the Principles of operation of automatic voltage regulator?
The principles of operation of the automatic voltage regulator is that of the excitation system. The working principle is to regulate the flow of reinforcement on the exciter.
In what situation voltage feedback amplifier is used?
in automatic volume contrrol

How does the variation of excitation of an alternator correct power factor?
The rotor of an alternator need a DC voltage applied to it to generate a magnetic field, this magnetic field will generate the AC power in the AC windings.The AVR(Automatic Voltage Regulator) is regulating this DC voltage so that the magnetic field is strong enough to maintain the output AC voltage. As soon as more current is drawn from the output, this output voltage will drop and a stronger magnetic field is needed to sustain the output voltage, so the AVR step up the exiting voltage to get a stronger magnetic field to compensate for the voltage loss in the AC windings.
Where can you buy an automatic Standa voltage regulator?
You can buy on ap standa voltage regulator in Hanoi, and buy in many many this products on ap standa in Vietnam.See related link below.
Is a potentiometer and voltage regulator the same thing?
No. A potentiometer is a variable resistor that allows you to set a voltage ratio or to adjust a resistance in a circuit. A voltage regulator, on the other hand, is a device that responds to changes in load, making automatic correction of output voltage. If you increase the load on a potentiometer, the output voltage will change, but not so (within limits) for a voltage regulator. However, you can use a potentiometer in a voltage regulator to make the output adjustable.
What is avr in turbo generator in thermal power plant?
AVR stands for automatic voltage regulator.
What is the purpose of the automatic voltage regulator?
The purpose of an adjustable voltage regulator is to have a regulator that can give out variable voltages. This is in contrast to a fixed voltage regulator which only outputs one voltage, which it is rated for. To allow for adjustable voltage, usually the resistors on the output of the regulator just need to be swapped for different values to give differing output voltages.
Were do you buy a voltage amplifier?
In audio look at an amplifier. It will be always a voltage amplifier.
What are voltage stabilizers?
Voltage Stabilizer is also called Automatic Voltage Stabilizer or AC Voltage Stabilizer or Voltage Regulator. Actually an automatic voltage stabilizer is designed to automatically maintain a constant voltage level, with protections of equipment against voltage surges, over voltage, under voltage, smoothing impulsive noise.
What are the use of the AVR?
Automatic voltage regulator is called as AVR. It is designed to automatically maintain a constant voltage level. It uses an electromechanical mechanism.
