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
