Description
AS**0 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%.
