摘　　要：本文提出了一种三电平PWM整流器的SVPWM算法。这种算法是将参考电压矢量转换到60°坐标系,然后再经过简单的算术运算即可计算出各基本矢量作用时间,避免了大量三角函数的运算。通过Matlab建立了三相三电平PWM整流器的电压定向控制系统的仿真模型,对该算法进行了仿真研究,结果验证了该算法的有效性。A SVPWM algorithm for three-level PWM Rectifier was presented in this paper. This algorithm is that the referencevector is first transformed into the sixty-degree coordinate system, then the duration time of the basic vec tot can be calculated just through some simple arithmetic operations, avoiding a large number of trigonometric calculations. The simulation of voltage oriented control system for three phase three-level voltage- source PWM rectifier is set up through the Matlab. Simulation results prove the validity of the algorithm.
