CONTROLFUNCTIONS - 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
connected 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 0.001μF (500V)
capacitors. This interface supports current sharing and is fault
tolerant except for the communication bus. See Figure 10.

The +Out and

Out power buses should be
designed to minimize and balance parasitic
impedance from each module output to the load.
The +Sense pins should be tied to the same
point on the +Out power bus; the

power bus.
At the discretion of the power system designer,
a subset of all modules within an array may be
configured as slaves by shorting SC to

ing diodes may be inserted in series with
the +Out pins of each module to provide
