What’s the automatic voltage regulators’ function?

Automatic Voltage Regulator (AVR), is a kind of electric controller. It could control the circuit voltage automatically. In this way, it could guarantee that the electrical equipment was working in safety and stability. To find the voltage in a circuit and then to control the components such as resistor and capacitor to adjust the electric current and the frequency, making the voltage stable. AVRs are extensively applied in air Conditioners, water Pumps, lighting, etc., to guarantee the healthy work of the equipment.

1. It can automatically adjust voltage changes in the circuit, so that electric equipment can work properly under both high-voltage, low-voltage and various voltage changes. So it works on all occasions where voltage may change.

2. Protection of equipment safe operation AVR keep the voltage at the level the circuit needs so that the device is not ruined with too much or too little voltage; therefore it extends the devices lifespan

3. Energy savings: The AVR can control the amount of current and the frequency so the equipment can be used at anytime and to save energy and reduce energy loss.

4. Improves efficiency: An AVR is going to correct the voltage in circuit automatically. so all device will work properly in their respective condition which can increase productivity as well as efficiency.

Automatic Voltage Regulator Principle

Automatic voltage regulator operates based on a principle somewhere between automatic voltage regulators and automatic constant voltage regulators which uses the transformer principle. Its most basic function is to control the number of turns of the transformer as well as its conduction time by controlling the voltage of the circuit to determine both the voltage and its stabilities.
