SB3000 Local Tunable Variables B-3
VDC_KD% Voltage Loop Derivative Gain
The value in this variable selects the voltage
loop derivative gain. This value should normally
be set to 0. Units: None
Default Value: 0
Low Limit: 0
High Limit: 400
Step: 1
VDC_WCO% Voltage Loop Crossover Frequency
The value in this variable selects the desired
response of the voltage loop. The higher the
value, the more quickly the rectifier responds to
a change in voltage reference. The value is
entered in radians/second. Units: rads/sec
Default Value: 300
Low Limit: 100
High Limit: 500
Step: 1
The factory default value of 300 rad/sec is the recommended value. System
operation should be tested at this level before any adjustments are made. Note that
if this value is adjusted too high, the voltage loop will become unstable.
