FIELD: electricity.
SUBSTANCE: invention is attributed to automatic control and motion-code conversion field, namely to shaft position transducers. Circuit for compensation of output voltages difference for quadrature power supply is introduced into shaft rotation angle converter. This allows to virtually entirely exclude error determined by difference of quadrature power supply output voltages, occurring due to temperature and time instability of parametres and to lower requirements to quadrature power supply parametres.
EFFECT: increase in of shaft rotation angle-to-code conversion precision.
