Description
MX**1 is a
two phase sensed Automatic Voltage
Regulator and
forms piece of the excitation structure for a
brush-less
generator. Excitation control is derived from a
three-phase
permanent magnet generator (PMG), to
isolate the
AVR power circuits from the effects of nonlinear
loads and to
reduce radio frequency interference on
the generator
terminals. constant generator short circuit
current is
another feature of the PMG system.
The AVR
senses the voltage in the central generator
winding and
controls the power fed to the exciter stator
and hence the
main rotor to keep the generator output
voltage
within the specified limits, compensating for
load,
speed,
temperature and power factor of the generator.
Soft start
circuitry is included to provide a even
controlled
build up of generator output voltage.
