Abstract :
In this paper, an uniform mathematic model of three-level inverters feed induction motor drives system has been constructed. Based on the application of the discrete space vector modulation (DSVM), a DTC strategy of three-level inverters induction motor drives system is proposed. With DSVM-DTC algorithm, the neutral-point (NP) voltage balancing problem and high dv/dt of output voltage is restrained. The proposed algorithm does not deteriorate dynamic performance of traditional DTC schemes, and does not increase switching loss at the same time. The experimental results verify the correctness and feasibility of the proposed control scheme.
