AVR AS440 Generator
The AS440 AVR generator is a half-wave phase controlled AVR thyristor type and is part of the excitation system for the brush-less generator. The design uses Surface Mount Technology (SMT) for high-integration features in a small AVR footprint.
The positive voltage of the residual level is ensured by the efficient use of semiconductors in the AVR power circuit. Power and voltage sensing circuits have separate terminals, allowing the excitation power to be lowered directly from stator winding for basic applications or from auxiliary winding if sustained short-circuit performance is required.
The Automatic Voltage Regulator is connected to the main stator winding and the exciter field winding to provide closed-loop control of the output voltage with the load setting of +/- 1.0%.
