Component Functions
•
AC line power supply to the
adjustable frequency drive.
•
The rectifier bridge converts
the AC input to DC current to
supply inverter power.
•
Intermediate DC bus circuit
handles the DC current.
•
Filters the intermediate DC
circuit current.
•
Provides line transient
protection.
•
Reduces the root mean square
(RMS) current.
•
Raises the power factor
reflected back to the line.
•
Reduces harmonics on the AC
input.
•
Stores the DC power.
•
Provides ride-through
protection for short power
losses.
•
Converts the DC into a
controlled PWM AC waveform
for a controlled variable
output to the motor.
•
Regulated 3-phase output
power to the motor.
•
Input power, internal
processing, output and motor
current are monitored to
provide efficient operation
and control.
•
User interface and external
commands are monitored and
performed.
•
Status output and control can
be provided.
