用于正弦输入线电流注入的广义三角形连接自耦变压器与隔离式SEPIC变换器优化12脉冲整流器

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 im...
