Abstract

This paper presents simplified method for space vector modulation of three-level converter, which based on the nonorthogonal frame. Using the peculiarity of nonorthogonal vector space, a new simple implementation without looking up table is proposed in this paper. This new method includes only two steps and assures both the optimal switching sequences and the simplicity of nonorthogonal algorithm. The results of simulation and experiment in comparison with conventional orthogonal algorithm are presented, which verify that the same output waveform and harmonic performance could be maintained.
