中文摘要：
针对基于圆形变压器的新型二十四脉波整流器的谐波问题进行了研究。首先,分析了三/十二相圆形变压器应用于二十四脉波整流的原理;然后,在磁动势平衡原理的基础上,对电网侧电流的谐波成分进行了理论和实验研究。实验结果表明：该新型整流器不仅能够提高输出直流电压的品质,还能有效地抑制输入侧的低次电流谐波。
英文摘要：
This paper focuses on the harmonic problem of a novel 24-pulse rectifier based on roundshaped transformer.It first presents the principle of 24-pulse rectifier with round-shaped transformer.Then harmonic currents on line-side are investigated based on the theory of magnetomotive force.The experimental results show that besides substantially improving the quality of output voltage,such round-shaped transformers applied in multi-pulse rectifier eliminate low order harmonics in primary currents effectively.
