Aimed at the problem that the three-level voltage space vector pulse width modulation method will cause the generation of common-mode voltage (CMV) in an inverter, a simplified modulation method that can reduce the CMC is proposed in this paper. First, the three-level voltage space vector diagram is simplified to a two-level space vector diagram by coordinate translation. Second, according to the principle of generating CMV by switching states, suitable vectors are selected to adjust the switching sequence of space vectors. Finally, the unified expression of modulated wave is obtained by derivation. A comparison with experimental results shows that the proposed method can effectively reduce the computational load and limit the CMV to 1/6 of the DC-side voltage.
