The Characteristics of unbalanced voltage operation for induction motor which has rectifier circuit in the secondary side are analyzed using a six elements ac circuit model referred to the primary side. The symmetrical component method is used to analyze motor performance and the positive and negative sequence circuit model are composed by taking account of the current overlap angle and the voltage drop of rectifier circuit. The characteristics of induction motor under unbalanced symmetrical voltage are computed and compared with the measured values to verify the proposed method
