Abstract: Cascaded multilevel conversion technology facilitates the realization of high efficiency, high power density and high modularity in low voltage AC/DC converters, but the traditional cascaded multilevel power factor correction rectifier has serious common-mode noise interference problems and high-frequency circulation problems. In view of this, a new type of single-phase cascaded half-bridge three-level PFC rectifier and cascaded full-bridge five-level PFC rectifier without increasing the circuit cost is proposed in this paper. First, by analyzing the causes of common-mode noise interference in the traditional cascaded topologies, the improved topologies that can suppress common-mode noise interference are deduced. Secondly, the circuit superposition theorem is used to analyze the common mode and circulation of the proposed PFC rectifiers in detail. Finally, experimental prototypes of a new type of cascaded half-bridge and cascaded full-bridge rectifiers was built in the laboratory, and the experimental results verified the effectiveness of the proposed topologies on common-mode noise suppression, circulation suppression, and efficiency improvement without the increase of circuit costs.
