Zusammenfassung:	To enhance the harmonic mitigation capacity of the 12-pulse rectifier, a series-connected 24-pulse rectifier with passive current injection circuit based on dual auxiliary transformers (PCIC-DAT) is proposed. The proposed PCIC-DAT is installed on the dc side of the proposed rectifier in parallel. The PCIC-DAT generates a specific square-wave current firstly, then the square-wave current is injected into the connection point of the two three-phase bridge rectifiers (TPBRs) so that the working modes of two TPBRs can be increased, and the series-connected 12-pulse rectifier is converted into a new 24-pulse rectifier subsequently. The resulting rectifier draws an approximately sinusoidal input current (THD
