摘要（英）：

The invention provides a pulse width modulation method based on a three-phase rectifier. The method comprises the following steps of establishing a mathematical model of the rectifier in a three-phasestatic coordinate system; transforming the mathematical model of the rectifier in the three-phase static coordinate system into an alphabeta coordinate system, introducing variables Sx and Sy and determining a switching state of a bridge arm of each phase of the rectifier; and controlling the rectifier according to the switching state of the bridge arm of each phase of the rectifier. According tothe pulse width modulation method based on the three-phase rectifier, which is provided by the invention, compared with a traditional pulse width modulation method, the calculation amount is reduced,and thus the efficiency is improved; and the requirement for timeliness can be met without using a high-precision processor, good economic benefits are obtained, and the application of a pulse widthmodulation technology is promoted.,
