| 摘要: |
| 研究了一种具有特殊结构的相间耦合电抗器，它可以迫使其输出电流产生一定角度的相移。对相间耦合电抗器的移相机理进行了深入研究，确定了针对特定移相角的电抗器的绕组匝数，并推导出了移相电抗器的输出电压和等效输入阻抗的表达式。对相间耦合电抗器在多脉动整流系统中的应用进行了介绍，指出通过选择合适的移相角可用于构成多脉动的整流系统，以代替移相变压器，并且能够达到相同的谐波抑制效果。对相间耦合电抗器的移相机理进行了仿真验证，结果证实了理论分析的正确性。还分别对由相间耦合电抗器构成的12脉动和24脉动整流器进行了仿真和实验研究，结果表明它的确能达到与移相变压器相同的谐波抑制效果。 |

| Abstract: |
| An inter-phase coupling reactor with peculiar structure is studied，which forces its output current to shift a certain phase angle. The principle of reactor phase-shifting is analyzed，the winding turns corresponding to a certain phase-shifting angle are determined，and the expressions of the output voltage and equivalent input impedance are deduced. The application of reactor in multi-pulse rectifier system is introduced. It is pointed out that，the inter-phase coupling reactor with suitable phase-shifting angle can be used to replace the phase-shifting transformer in the multi-pulse rectifier system with same harmonic suppression effect. Simulative results verify the correctness of theoretical analysis. Simulation and experiment are also carried out respectively for 12-pulse and 24-pulse rectifiers composed of the inter-phase coupling reactor and the results show that it has the same harmonic suppression effect as the phase-shifting transformer. |
