摘要 论述了二极管钳位式三电平逆变器的SVPWM(空间矢量脉宽调制)控制原理与实现方法。提出了确定参考矢量的3个规则,并推导出工作矢量作用时间、输出顺序,描述了中点电位的控制规则。通过采用Matlab仿真,证明三电平逆变器的SVPWM控制的可行性。 The principle and implement method of space vector pulse width modify (SVPWM) controlling diode clamped three level converter are discussed. Three judging rules for determining the location of the desired vector are proposed, the duty time of active vectors, output sequence are deduced, and the neutral point potential rule is described. The simulation results through Matlab verify the affectivity Of SVPWM controlling of three-level converter.
