38.8.1.3 The Indirect Current Control Technique of SAPF
In the indirect current control technique, the switching signals for SAPF devices are obtained by com-
parison of reference (

) and sensed (i
s1
, i
s2
and i
s3
) source currents [19,20]. e d and q axes
reference supply currents are expressed as follows:
