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 cur-
rent 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 .001F (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.
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 –Out.
OR’ing diodes may be
inserted in series with the
+Out pin of each module to
provide output fault tolerance.
As an example, the circuit
shown may be used to
compensate for the voltage
drop of the diode.
This module is designed for
point of load regulation, where
remote sensing is not required.
Active compensation, as
shown here, may be used in
applications with significant
distribution losses.
