摘要

摘要: 針對目前18脈沖自耦變壓器輸出電壓難以調節的問題，在保持現有18脈沖自耦變壓器優勢的基礎上，提出一種新型降壓式18脈沖自耦變壓器拓撲結構并對其進行優化.變壓器通過每相原邊延長繞組與副邊移相繞組的連接實現對輸出電壓的寬范圍降壓調節.考慮到延長繞組與副邊移相繞組連接抽頭的位置變化對變壓器性能的影響，以變壓器降壓比及延長繞組連接抽頭的位置系數為變量，理論推導不同情況下變壓器的通用設計公式，并進行仿真分析，得到相同降壓比條件下降壓式自耦變壓器等效容量最小的最優連接抽頭位置.最后通過實驗驗證了設計的合理性.

Abstract: Aiming at the requirement for voltage regulation with a 18-pulse autotransformer-rectifier, a novel step-down 18-pulse topology was designed and optimized based on the advantage of present topologies. The primary extended winding of the step-down 18-pulse autotransformer-rectifier was connected with the winding tap of the phase shift secondary winding to reduce the transformer input voltage. Considering the influence caused by the position change of the connecting tap between the primary extended windings and secondary phase shift windings on the autotransformer performance, transformer voltage ratio and winding tap position were regarded as variables. A universal design formula was derived and simulation analysis was carried out to obtain the optimal connection tap position with the minimum equivalent capacity of the step-down autotransformer under the same voltage ratio. Finally, the rationality of the design is verified by experiments.
