The interphase reactor (IPR) is one of the most important components of the passive harmonic reduction circuit (HRC), and the optimum turns ratio design of the IPR is of great significance to ensure the effect of the passive HRC. In combination with the pulse number multiplication methods, the configuration of the multipulse rectifiers (MPRs) with single/dual/triple-passive HRCs are constructed, respectively. The general optimum turns ratio design method for the IPRs is proposed, which contains most of the realizable combinations of the HRCs. The relationship between the turns ratio of the IPR and the phase number of the bridge rectifier in the main circuit is established, the influence of the turns ratio selection on the power quality of the MPRs is presented. In addition, this article takes N equal to five as an example to verify the effectiveness of the proposed general optimum turns ratio design method of IPR. The power quality of the MPRs with different HRCs or phase number are compared. All the research can provide a useful guideline and theoretical foundation for the MPR selection and the HRC design under the specific occasions.

超多相并联多脉冲整流器直流侧无源谐波降低方法研究

相间电抗器（IPR）是无源谐波降低电路（HRC）的重要组成部分之一，IPR的最优匝数比设计对于保证无源HRC的效果具有重要意义。结合脉冲数倍增方法，分别构建了具有单/双/三无源HRC的多脉冲整流器（MPR）的配置。提出了IPR的一般最优匝数比设计方法，该方法包含了大多数可实现的HRC组合。建立了IPR匝数比与主电路桥式整流器相数的关系，给出了匝数比选择对MPR电能质量的影响。另外，本文取以N等于5为例，验证了提出的IPR通用最优匝数比设计方法的有效性。比较不同 HRC 或相数的 MPR 的电能质量。上述研究可为特定场合下的MPR选型和HRC设计提供有益的指导和理论基础。
