Summary In this paper, a novel full‐wave 12‐pulse rectifier with simple circuit configuration is proposed. The proposed full‐wave 12‐pulse rectifier consists of a conventional six‐pulse full‐wave rectifier and an auxiliary single‐phase full‐bridge rectifier (ASFR). The ASFR extracts a rectangular current from the DC side of the rectifier to increase the output states of two three‐phase half‐wave rectifiers, then the conventional six‐pulse full‐wave rectifier is upgraded to a 12‐pulse full‐wave rectifier in accordance with the current relationship between AC and DC sides and the relationship between DC‐side voltages. Since only a low‐capacity ASFR (6.3% P d ) is needed, the proposed 12‐pulse rectifier has the least number of components count, making it robust and simple to implement. The average output current of ASFR is only 6.7% of the load current, which makes it more suitable for low‐voltage and high‐current applications. A prototype with a power of 1 kW is built to verify the correctness of the theoretical analysis.
