CONTROL FUNCTIONS - PR PIN
Parallel Operation
The PR pin supports paralleling for increased power with N+1
(N+M) redundancy and phased array capability. Modules of
the same input voltage, output voltage, and power level will
current share if all PR pins are suitably interfaced.
Compatible interface architectures include the following:
DC coupled single-wire interface. All PR pins are directly con-
nected to one another. This interface supports current sharing
but is not fault tolerant. Minus In pins must be tied to the same
electric potential. See Figure 9.
AC coupled single-wire interface. All PR pins are connected to
a single communication bus through .001F (500V) capacitors.
This interface supports current sharing and is fault tolerant
except for the communication bus. See Figure 10.
