Abstract This paper proposed a novel and passive harmonic reduction method at dc link of multi-pulse rectifier. The proposed method used a single-phase diode-bridge rectifier to generate circulating current which can shape the input line current of multi-pulse rectifier. The input side of the single-phase diode-bridge rectifier was connected with the secondary winding of inter-phase reactor, and its output side was connected with load, which can recycle the harmonic energy and feed to load. The operation mode of the single-phase diode-bridge rectifier was analyzed, and the turn ratio of the IPR was designed optimally. Under ideal condition, the proposed multi-pulse rectifier operates as a 24-pulse rectifier, and its THD of input line current is about 7.6%. In addition, the proposed multi-pulse rectifier is easy to realize, and its cost of harmonic reduction is low. Simulation and experiment results show that the THD of input line current is less than 5%.
