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. Negative In pins must be tied
to the same electric potential. Up to three converters may be
paralleled by this method. See Figure 9.
AC coupled single-wire interface. All PR pins are connected
to a single communication bus through 0.001 μF (500 V)
capacitors. This interface supports current sharing and is fault
tolerant except for the communication bus. Up to three
converters may be paralleled by this method. See Figure 10.
Transformer coupled interface. For paralleling four or more
converters a transformer coupled interface is required. For
details on this configuration please refer to the design guide
referenced in the following technical information section.
