ABSTRACT:
A solid state synchro torque receiver driver that uses unfiltered AC as the power source and push-pull regulating transistors operating in the linear mode to drive the torque receiver stator loads. A feedback amplifier compares the push-pull outputted AC signal against an inputted AC data reference (i.e. the desired stator excitation amplitude) and thus closes the loop forcing the output to follow the input. The synchro torque receiver operates in a closed loop and thus has realizable potential of near infinite resolution and high accuracy.
