TRANSFORMER CONSIDERATIONS FOR
BU-63825X3 (+5V ONLY VERSIONS)
In selecting isolation transformers to be used for the BU-
63825X3 (+5V only) versions, there is a limitation on the maxi-
mum amount of leakage inductance. If this limit is exceeded, the
transmitter rise and fall times may increase, possibly causing the
bus amplitude to fall below the minimum level required by MIL-
STD-1553. In addition, an excessive leakage imbalance may
result in a transformer dynamic offset that exceeds 1553 specifi-
cations.
The maximum allowable leakage inductance is 6.0 H, and
is measured as follows:
The side of the transformer that connects to the Hybrid is defined
as the “primary” winding. If one side of the primary is shorted to
the primary center-tap, the inductance should be measured
across the “secondary” (stub side) winding. This inductance must
be less than 6.0 H. Similarly, if the other side of the primary is
shorted to the primary center-tap, the inductance measured
across the “secondary” (stub side) winding must also be less
than 6.0 H.
The difference between these two measurements is the
“differential” leakage inductance. This value must be less than
1.0 H.
Beta Transformer Technology Corporation (BTTC), a subsidiary
of DDC, manufactures transformers in a variety of mechanical
configurations with the required turns ratios of 1:2.5 direct cou-
pled, and 1:1.79 transformer coupled. Table 33 provides a listing
of many of these transformers. For further information, contact
BTTC at 631-244-7393 or at www.bttc-beta.com.
