Generators with automatic voltage regulator (AVR)

 

— automatic regulator that allows you to maintain a constant voltage level at the generator output. Such a regulator smoothes out the differences that occur due to changes in engine speed; this is especially important when connecting devices that are sensitive to power stability. It is worth noting that the presence of AVR is practically mandatory for synchronous generators (see "Alternator"), but this function is not found in other varieties: in asynchronous and duplex units, it is not applicable in principle, and in inverter units, the role of the regulator is played by the inverter itself, and they do not require additional electronics.
