摘要
随着交流电力推进技术在船舶行业的广泛应用,变频器等电力电子设备也被广泛的使用,变频器在输入回路会产生大量谐波。本文通过分析六脉动整流、12脉动整流、24脉动整流时电网的谐波含量,得出多相整流可以有效减小电网谐波的结论,最后提出了24脉动整流变压器的一种实现方案。
As wide application of electric propulsion technology in ship NMB, adjustable speed system driven by frequency converters is mainly used. The frequency converter products a great quantity of harmonics in input circuit. By analyzing the harmonic caused in 6-pulse, 12-pulse and 24-pulse rectification, the paper gives a conclusion that multiphase rectification is used effectively to reduce the harmonic, and presents a design of 24-pulse rectifier transformer.
