| Abstract: | As to the five-phase three-level inverter, the number of voltage space vectors is so large, which leads to so complicated algorithm. In this paper, the sinusoidal PWM method is adopted, and the total harmonic content of the output voltage can be lower and the algorithm can be easily realized. At the same time, during the real control process, zero-order component harmonic wave can be easily injected to optimize the algorithm so that the ideal output voltage can be obtained. The theoretical results are validated by simulation. |
