Abstract
This disclosure describes a device for converting binary coded angle information into the analog angular position of the rotor winding of a conventional counter-reaction resolver. The device is operative to provide two periodic rectangular wave signals of equal amplitudes and of time durations respectively proportional to the absolute values of the sine and cosine of the angle. These periodic rectangular wave signals are respectively applied to the stator windings of the resolver via two amplifiers respectively. Each of these amplifiers comprises a counter-reaction loop comprising a compensation winding and a capacitor. The rotor winding of the resolver is inserted in a servocontrol loop comprising an amplifier and a commutator which are connected only in the simultaneous absence of the two periodical rectangular wave signals.
