8.5.2.1 Setting target cos
φ
The desired value of target cos
φ
can be set from 0.80 inductive to 0.90 capacitive in increments
of 0.01.
The mode of operation of this adjustment can be seen in
[Figure 44]
and
[Figure 45]
.
If the system operates within the band range shown, no switching operations will be activated.
However, if the system operates outside the band range, the PQC will try to return to within the
band range with the minimum number of switching cycles.
