相選擇輸出
兩鄰相在15°的電角度內(nèi),可以產(chǎn)生期望轉(zhuǎn)矩。在8/6 SRM中,一個周期有四個不同的激勵區(qū)域,但只有兩相產(chǎn)生期望轉(zhuǎn)矩是有用的。一個周期內(nèi),轉(zhuǎn)矩的正負、轉(zhuǎn)子位置信號和想選擇信號對應(yīng)的關(guān)系如表一所示,輸出的相選擇信號直接輸入TDF和CCG模塊,進行各相轉(zhuǎn)矩和電流的求取。

表一中1為選擇該相,0為不選擇該相。
3.3 功率變換器選取
功率變換器采用非對稱的半橋變換器,如圖3所示。此種變換器單電源供電,每相兩個主開關(guān),工作原理簡單。
