摘　　要：多电平逆变器被广泛地应用于高压大功率工业领域,但是随着电平级数的增加,其空间矢量调制算法(SVPWM)也越来越复杂。研究一种基于两电平的新型5电平SVPWM算法,该算法易于确定参考矢量的位置及其作用时间。以5电平NPC/H逆变器为例解释该算法,该算法可以非常容易地推广到更多电平级数的逆变器中。最后,实验波形验证了该算法的正确性。The multi-level inverter is widely used in high power,high voltage application.However,the implementation of the space vector modulation（SVPWM） for a multi-level inverter is more and more complex as level of inverter increasing.A new SVPWM algorithm for five-level inverters was researched based on standard two-level SVPWM.The new SVPWM method is easy to determinate the location of the reference vector and calculate the ontimes.A five-level NPC/H inverter is used to explain the method.The method can be easily extended to a multi level inverter.Finally,experimental results verify the validity of the method.
