| Abstract: | For its excellent performance, three-level converter has replaced the traditional two-level converter and became one of the main methods of speed modulation of large capacity high voltage motor. But various output states need high requirements for its control algorithm. Based on the concept of the basic structure, the algorithm of space voltage vector pulse width modulation is analysed, which can be used to control the three-level converter. Then the flow chart of simulation by MATLAB is demonstrated and the advantages of three-level converter is confirmed. The results can be used for further development of new converter. |
