The Electronic (Type) Automatic Voltage Regulator

The electronic (type) automatic voltage regulator has evolved with the advancements in power semiconductors over the past 20 years. Unlike the mechanical voltage regulator, the electronic voltage regulator is only used in power quality applications since it is designed for low voltage (< 600V) and its higher performance is not necessarily an advantage in line drop compensation applications.

As electronics become more prevalent in industrial and commercial applications, the speed and performance advantages of the electronic voltage regulator make it a better fit than the mechanical voltage regulator.
