CONTROL FUNCTIONS - PR PIN

Parallel Operation

sharing but is not fault tolerant. Minus In pins must be tied to

the same electric potential. See Figure 9.

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.

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.

Compatible interface architectures include the following:

DC coupled single-wire interface. All PR pins are directly

connected to one another. This interface supports current

• The +Out and –Out power buses should be

designed to minimize and balance parasitic

impedance from each module output to the load.
