| Abstract: | SVPWM is an important content in the teaching of power electronic technology. In this paper, the teaching focus of space vector modulation is comprehensively and systematically combed. This paper focuses on the core idea of SVPWM, especially the basic principle of three-phase sinusoidal AC SVPWM. At the same time, it is proved that under SVPWM, the maximum circle of the inverter output is a regular hexagon formed by the basic space vector, and the utilization rate of DC bus voltage is increased by about 15.4%. |
