12.0 CURRENT SHARING
The performance of the SAC? topology is based 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 a positive
temperature coefficient series resistance.
This type of characteristic is close to the impedance
characteristic of a DC power distribution system both in
dynamic (AC) behavior and for steady state (DC) operation.
When multiple BCM ? modules of a given part number are
connected in an array they will inherently share the load
current according to the equivalent impedance divider that the
system implements from the power source to the point of load.
Some general recommendations to achieve matched array
impedances include:
? Dedicate common copper planes within the PCB
to deliver and return the current to the modules.
? Provide as symmetric a PCB layout as possible among modules
? Apply same input / output filters (if present) to each unit.
For further details see AN:016 Using BCM ? Bus Converters
in High Power Arrays .
13.0 FUSE SELECTION
In order to provide flexibility in configuring power systems
VI Chip ? modules are not internally fused. Input line fusing
of VI Chip ? products is recommended at system level to
provide thermal protection in case of catastrophic failure.
The fuse shall be selected by closely matching system
requirements with the following characteristics:
? Current rating (usually greater than maximum current
of BCM ? module)
? Maximum voltage rating (usually greater than the maximum
possible input voltage)
? Ambient temperature
? Nominal melting I 2 t
? Recommend fuse: <= 10A Littlefuse Nano 2 Fuse.
14.0 REVERSE OPERATION
BCM ? modules are capable of reverse power operation. Once
the unit is started, energy will be transferred from secondary
back to the primary whenever the secondary voltage exceeds
VIN ? K. The module will continue operation in this fashion for
as long as no faults occur.
The BCM48BF120T300A00 has not been qualified for
continuous operation in a reverse power condition.
Furthermore fault protections which help protect the module in

forward operation will not fully protect the module in reverse
operation.
Transient operation in reverse is expected in cases where there
is significant energy storage on the output and transient

voltages appear on the input. Transient reverse power

has been qualified to cover these cases.
