V375B24C400A3 数据手册

CONTROL FUNCTIONS - PR PIN

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.

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.

AC coupled single-wire interface. All PR pins are connected to

a single communication bus through ^.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.
