| 摘要: |
| 为降低多脉波整流系统设计成本，提高谐波抑制效率，对原边为三角形联结的自耦变压器进行了优化设计。通过几何方法分析自耦变压器相量图，给出了原边为三角形联结的自耦变压器所有副边位置；并通过分析副边位置系数和比例系数的关系，推导出不同变比时自耦变压器通用设计公式；同时分析了自耦变压器结构参数与其等效容量的关系，通过图表法得到等效容量最小时的结构参数。仿真和实验结果验证了理论分析的正确性。 |

| Abstract: |
| The autotransformer with delta-connected primary winding is optimally designed to lower the cost of multi-pulse AC-DC converter and enhance the efficiency of harmonic elimination. The phasor diagram of autotransformer is analyzed by geometry method and its connection of secondary windings is presented. The generalized design formula of autotransformer for different turn ratios is deduced based on the relationship between the position and proportion parameters of secondary windings. The configuration parameter of autotransformer with the minimum equivalent capacity is obtained by the diagram method based on the relationship between the configuration parameter and the equivalent capacity. Simulation and experiment show the correctness of theoretical analysis. |
