AVR AS440 for generators

AS440 is a half wave phase restricted thyristor type AVR and forms part of the excitation system for a brushless generator. The propose employs Surface Mount Technology (SMT) for high integration of features in a minute footprint AVR. Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. The control and voltage sensing circuits have separate terminals, allowing the excitation power to be resulting directly from the stator winding for necessary applications or from an auxiliary winding if sustained short circuit performance is essential. The AVR is linked with the main stator windings and the exciter field windings to present closed loop control of the output voltage with load regulation of +/- 1.0%.
