Abstract:

A method of three-level SVPWM without large vectors is proposed,which is able to reduce vectors and vector regions and simplify algorithm by using the remaining 3 zero vectors,12 small vectors and 6 medium vectors to re-divide the vector space into 18 effective regions with 6 large vectors eliminated.On the basis of studying the traditional three-level SVPWM diagram deeply,this method is obtained with reminding vectors for dividing sectors and arranging switch sequence with large vectors eliminated.It is applied in direct torque control system for simulation analysis,which verifies its feasibility and validity.

Key words: three-level, SVPWM, unused large vectors, direct torque control
