Figure 11 — N+1 module array output connections.

• 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 –Sense pins

should be tied to the same point on the –Out

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 –S.

• ORʼing diodes may be inserted in series with

the +Out pins of each module to provide module

output fault tolerance.
