primary function is also listed.
FUNCTION
Regulates current in the alternator field based on firing
pulses from the PSC.
Attenuates high voltage output from the AFSE to an
acceptable level for use by the Analog I/O card in the
PSC.
Main alternator, propulsion and control system.
Provides signal conditioning for analog signals to and
from the TCI and PSC.
A 3-phase, AC induction motor mounted in the blower
assembly behind the electrical cabinet. Used to drive two
blowers for cooling the traction motors and control
cabinet components.
Used with the AXIND to filter the regulated DC voltage
from the Auxiliary Phase Control Rectifier into a smooth
DC supply suitable for use by the Auxiliary Power Inverter.
Provide overload protection for the Auxiliary Power
Inverter/Phase Control Rectifier.
Used with the AXCAP to filter the regulated DC voltage
from the Auxiliary Phase Control Rectifier into a smooth
DC supply suitable for use by the Auxiliary Power Inverter
The Auxiliary Phase Control Rectifier converts the
3-phase, AC input voltage from the Alternator to
regulated DC voltage and supplies the regulated voltage
through a filter to the Auxiliary Power Inverter. The
Auxiliary Power Inverter inverts the regulated, filtered, DC
voltage into a variable voltage, variable frequency,
3-phase output to power the Auxiliary Blower Motor.
Monitors frequency of the tertiary winding and provides a
sample of the frequency to the PSC, which uses the input
to synchronize the firing pulses sent to the Alternator
Field Static Exciter Panel (AFSE).
Attenuates high voltage from two phases of the Alternator
to a level acceptable to the Analog I/O card in the PSC.
