Rockwell Automation 2364F Regenerative DC Bus Supply Unit (RGU) - Manual (Page 34)

Publication 2364F-5.01– October 2003
1-18 Overview
Figure 1.22, Figure 1.23, and Figure 1.24 show the condition
where the RGU is regenerating power to the AC line and the
power factor is lagging since I
d
is commanding some positive
value.
