What does AVR mean?

An Automatic Voltage Regulator (AVR) is an electronic device that keeps the voltage supply at a set value and maintains a constant voltage. The voltage input in AVR is fluctuating or variable while the output is always constant. It provides stable voltage to the electronic equipment that curbs the problem of fluctuating voltage supply.

• Electronic devices such as television, refrigerator and desktop computer must have AVR to protect their electronic components from damage due to voltage surges.

There are two types of AVR

• Relay type
• Servo Motor type

AVR is used in

• 3D printing
• Electronic home appliances
• Power stations
• Ship electric power production

Advantages of automatic voltage regulator

• The speed of voltage correction is very fast.
• It needs low maintenance.
• The line isolation is quite good in AVR.
• AVR does not restrict the number of correction cycles.

Disadvantages of AVR

• This costs more than the mechanical voltage regulator.
• The overload capacity of the current is very poor.

Features of AVR

• It must be compatible with loading: A good AVR must be compatible with its load to operate and must not disturb the load sequence of other devices with a standard power supply.

• The voltage supply must be accurate: There must be accurate AVR voltage because the voltage accuracy is highly dependent on the critical load requirement.

• Regulation of voltage: The voltage regulation is affected by different factors such as the size of the cable, design of the circuit, etc. But a good AVR must have a voltage regulation of nearly equal to 0.1%.

• Range of input voltage: The essential feature you must look at in an AVR is its input voltage range. A suitable input voltage range gives voltage correction to the maximum extent.
