DATASHEET
PRELIMINARY BCM352F440T330A00 - BCM352T440T330A00
7.0 CURRENT SHARING
The SAC topology bases its performance on efficient transfer
of energy through a transformer, without the need of closed
loop control. For this reason, the transfer characteristic can be
approximated by an ideal transformer with some resistive drop
and positive temperature coefficient.
This type of characteristic is close to the impedance characteristic
of a DC power distribution system, both in behavior
(AC dynamic) and absolute value (DC dynamic).
When connected in an array (with same K factor), the BCM
module will inherently share the load current with parallel
units, according to the equivalent impedance divider that the
system implements from the power source to the point of load.
It is important to notice that, when successfully started, BCMs
are capable of bidirectional operations (reverse power transfer
is enabled if the BCM input falls within its operating range and
the BCM is otherwise enabled). In parallel arrays, because of
the resistive behavior, circulating currents are never experienced
(energy conservation law).
General recommendations to achieve matched array impedances
are (see also AN016 for further details):
? to dedicate common copper planes within the PCB to
deliver and return the current to the modules
? to make the PCB layout as symmetric as possible
? to apply same input/output filters (if present) to each unit
