Voltage Regulation & Power Conditioning

Automatic Voltage Stabilizer (AVR)

An automatic voltage regulator (AVR) is a device used in generators and power systems with the purpose of automatically regulating voltage, which means that it will turn fluctuating voltage levels into constant, safe voltage levels. Automatic voltage regulators (AVRs) work by stabilizing the output voltage of generators at variable loads, dividing the reactive load between generators running in parallel (voltage droop), and helping the generator respond to overloads. Putting it as simply as possible — an AVR continuously takes variable input voltage ranges and maintains a constant output at a fixed voltage.
