Abstract: The present disclosure relates to an apparatus for correcting a current reference, and more particularly, to an apparatus for correcting a current reference including a calculation unit configured to set a first torque reference section and a second torque reference section using candidate values of a correction factor that corrects the current reference so as to enable the current reference to satisfy rated operating conditions of the induction machine, and calculate the correction factor according to a section, in which the torque reference is included, of the first torque reference section and the second torque reference section, and a correction unit configured to correct the current reference using the correction factor.
