  1. Based on the investigation with several voltage control methods, such as venturini method, instantaneous double - voltage synthesis method and space vector modulation method ( svm ), three new control strategies are put forward. firstly, a time - varying modulation coefficient svm method is proposed to improve mc ' s anti - disturbance performance under the asymmetry input voltage. secondly, a 5 - state switching strategy is presented for mc controlled by the svm method, which reduces the commutation number and switching losses remarkably

    在分析了venturini控製法、瞬時雙電壓法、空間矢量法等電壓控制方法的基礎上,提出了在非對稱輸入條件下矩陣變換器空間矢量法的時變調制比改進控制策略,提高了變換器的抗干擾性能;對空間矢量法的開關策略進行了研究,提出了新型5狀態開關策略,在保證其他性能不受影響的條件下,減少了變換器的換流次數和開關損耗;提出了一種矩陣變換器單電壓合成的新方法,它不僅使得變換器的控制簡單,計算量減少,而且使得開關損耗達到最少。
