本文旨在探討一個以軟式切換直流鏈變頻器驅動永磁式同步伺服系統之設
計與研製。此種變頻器比傳統之變頻器的操作頻率還要高，並且有更好的
效率。一個三相、 4仟瓦、17仟赫的共振式直流鏈變頻器已經建立，並且
成功地驅動一個以磁場導向控制的永磁式同步伺服系統。本文中詳細說明
了整個系統的設計、模擬及實作，並加以分析。實驗研究提供了相關的模
擬與測量結果。所量測的波形也驗證了電腦結果。本文的實驗將可為設計
軟式切換變頻器驅動直流無刷伺服系統奠定一理論基礎。
This thesis presents a modeling and implementation of a
resonant dc-link inverter driving a permanent magnet
synchronous servo system. The inverter is operated at a
higher frequency and has higher efficiency than traditional
inverters. A 3-phase, 4KW, 17Khz resonant dc-link inverter
has been constructed and successfully tested to drive a
permanent magnet sychronous servo system based on field-
oriented control. A detail of modeling, simulation,
analysis, and implementation of the whole system is
described. Experimental case studies that correlate
simulation and measurement results are provided. The
measued waveforms verify the computer simulation results.
The experiment of the thesis can offer a design
procedure for a resonant dc-link inverter driving a dc
brushless servo system.
