The converter output current is typically limited (in the DSC-
10510 case to 0.8 A peak). This limits the power supply to more
reasonable values but introduces another problem – the torque
receiver can hang up in a continuous current limited condition at
a false stable null. The DSC-10510 has special circuits that
sense this continuous current overload condition and sends a
momentary 45° “kick” to the torque receiver thus knocking it off
the false null. The torque receiver will then swing to the correct
angle and properly null. If the torque receiver is stuck it will not
be able to swing off the over-current condition. In this case the
converter will send a BIT signal when the case temperature
exceeds 140°C. This BIT signal can be used to shut down the
output power stage.
An additional advantage of using pulsating power supplies is that
the loss of reference when driving torque loads is fail safe. The
load will pump up the ±V voltage through the power stage clamp
diodes and the loss of the reference detector will disable the
power stage. The power stage will be turned off with the required
power supply voltages. The pulsating power supply diodes will
isolate the pumped up pulsating supplies from the reference. If
the DC power supplies are to be used for the power stage, and
there is a possibility of the DC supplies being off while the refer-
ence to the torque receiver is on, then the protection circuitry
shown in Figure 11 is highly recommended.
A remote sense feature is incorporated in DDC’s DSC-10510
hybrid digital-to-synchro converter. Rated at 7 VA, it offers accu-
racies to ±2 minutes of arc at the load. This remote sense feature
operates just as other precision sources do. A separate line is
