This letter proposes a novel multipulse rectifier. The proposed rectifier is a combination of a novel dual-passive-harmonic-reduction method and a traditional double-star uncontrolled rectifier. The proposed method contains a multiwinding interphase reactor (IPR) and the corresponding auxiliary circuit. From the viewpoint of minimizing the total harmonic distortion (THD) of the input line current, the turn ratio of the multiwinding IPR is optimally designed. Under the optimal turn ratio, the proposed rectifier operates as an 18-pulse rectifier. Its theoretical THD of the input line current is about 10.1%, and its experimental THD is 6.58%. The proposed method is simple and easy to realize.
