Abstract
- This paper discusses an alternative to reduce harmonic current distortion in a 12-pulse rectifier. The circuit is based on a generalized autotransformer connection with low power-to-core that feeds two isolated SEPIC converters. Compared to other passive devices operating as conventional 12-pulse rectifiers, besides a tight dc bus, the use of static converters can, by means of an active current imposition, provide very low harmonic distortion of current. This paper presents a theoretical analysis which is corroborated by computational and experimental results. The results show that the performance of the proposed converter is similar to the performance provided by three-phase unity power factor PWM rectifiers, however, only two active switches are deployed.
