1.3. High voltage device operation modes
1.3.1 Terminology
Syntax
Declaration
V
nom
Voltage nominal, the maximum possible output voltage
I
nom
Current nominal, the maximum possible output current
V
set
Voltage Set, the user-controllable demanded output voltage
V
meas
Voltage Measure, the actual measured output voltage
V
lim
Voltage Limit. Can be a hardware or a software limit and serves two purposes:
1. It limits the upper value of V
set
to the given limit value: |V
set
|≤ V
lim
2. It generates the Channel Status is Voltage Limit if V
meas
exceeds the limit value
(the exact threshold value is device dependend)
I
set
Current Set, the user-controllable demanded output current
I
meas
Current Measure, the actual measured output current
I
lim
Current Limit. Can be a hardware or a software limit and serves two purposes:
1. It limits the upper value of I
set
to the given limit value: |I
set
|≤ I
lim
2. It generates the Channel Status is Current Limit if I
meas
exceeds the limit value
(the exact threshold value is device dependend)
V
bounds
Voltage bounds, a tolerance tube V
set
±
V
bounds
around V
set
. If V
meas
exceeds this tolerance in either direction,
the Channel Status is Voltage Bounds is generated. (condition: no ramping)
I
bounds
Current bounds, a tolerance tube I
set
±
I
bounds
around I
set
. If I
meas
exceeds this tolerance in either direction, the
Channel Status is Current Bounds is generated. (condition: no ramping)
