| 摘 要： | 在常规2电平空间矢量不连续调制策略的基础上,对应用于多电平逆变器的相应调制策略进行了研究。针对(Space Vector Pulse Width Modulation,SVPWM)不连续调制策略带来的输出电压不对称的缺点,提出了一种适用于欠调制区的不连续调制方法。实验结果证明,该方法既可减少开关损耗又可满足输出波形对称、输出谐波畸变率小的要求,是一种较为优良的应用于欠调制区域的调制方法。

| Abstract: | Based on two level space vector discontinuous modulation Strategies,this paper makes the research on multi-level inverter modulation Strategies. This paper presents a discontinuous modulation method applicable to the under modulation conditions avoiding the asymmetric output voltage in traditional discontinuous modulation. The experiment in-dicates that this method can reduce the switching loss and be able to meet the requirements of the output waveform sym-metry and small harmonic distortion factor. It is a good modulation method in the under modulation area. |
