• 中文摘要： 我們對於具有電壓源、電流源、與直流馬達負載的三相整流器提出其穩態分析的統一解析模型。我們假設直流側電流為連續導通模式並考慮引起換向效應的交流側電感。對於某特定觸發角與直流側電感，我們使用換向角為參數在輸出平面上畫出整流器輸出電壓對輸出電流的調整曲線。觸發角的上限可推導為直流側電感的函數。換向角的範圍可推導為觸發角與直流側電感的函數。因此對於某特定直流側電感，我們可求得輸出平面上的允許操作區域。
• 英文摘要： We propose an analytical model which unifies the steady state analysis of a three-phase rectifierwith voltage source, current source, and dc motor loads．The continuous conduction mode of the dc-side current is assumed，and the ac-side inductance which introduces the commutation effect is considered.The regulation curve of output voltage versus output current for the rectifier can be plotted on the outputplane using the commutation angle as the parameter under some specified firing angle and dc-sideinductance.The upper bound of the firing angle can be derived as a function of the dc-side inductance.The range of the commutation angle can be found as a function of the firing angle and the dc-side inductance.Then, the allowable operating region of the output plane for a certain dc-side inductance is determined.
