TRANSFORMERS
In selecting isolation transformers to be used with the Mini-ACE,
there is a limitation on the maximum amount of leakage induc-
tance. 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 dynam-
ic offset that exceeds 1553 specifications.
The maximum allowable leakage inductance is 6.0 H, and
is measured as follows:
The
side
of
the
transformer
that
connects
to
the
Mini-ACE 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) wind-
ing 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 3 provides a listing
of many of these transformers.
