Abstract

In a current detection apparatus, a corrector obtains first current-value pairs of the plural values of the corrective first phase current and the respective plural values of the corrective first phase bus-based current synchronized with the plural values of the corrective first phase current. The corrector obtains second current-value pairs of the plural values of the corrective second phase current and the respective plural values of the corrective second phase bus-based current synchronized with the plural pairs of the corrective second phase current. The corrector corrects at least target first and second phase currents detected by a first current detector based on the obtained first current-value pairs and the second current-value pairs to thereby align amplitudes of the respective target first and second phase currents with each other.
