摘要
阐述了动车组谐波产生的原因及多重四象限载波移相控制的原理,并通过试验的方式验证了载波移相控制的效果,试验结果表明,载波移相控制技术能有效地降低动车组网侧谐波含量。
This paper described the reasons for EMU harmonic generation and the carrier phase shift principle of multiple control of fourquadrant rectifier . It＇s effect was verified by experiment, which results showed that the carrier phase shift technology can effectively re duce the harmonic content caused by EMU.
