m) PF, the inductive or capacitive signed power factor
commanded for test
n) PFmid,cap = (1 + PFmin,cap)/2, middle of the EUT
capacitive range.
o) PFmid,ind = (1 + PFmin,ind)/2, middle of the EUT
inductive range.
p) POutlimit, the maximum output power either limited by the
input supply or by a command to the inverter.
q) PFtarget, the target power factor. This will differ from the
commanded power factor in ‘Active Power Priority’ modes
for input power greater than PX
