Abstract :
A novel modulation strategy for cascade multi-level converters, sample time staggered space vector modulation, is put forward in this paper. The equivalent switching frequency is improved and the harmonic component is greatly decreased under this technique. The frequency and harmonic feature is analyzed by simulation. The experimental result is in accord with the analysis.
