| 摘 要： | 在研究三电平空间矢量调制方法的基础上,提出将该方法用于能量回馈。分析了三电平空间矢量调制方法如何运用于逆变器中,给出了电压矢量作用时间的计算方法和如何用二电平简单判断三电平参考矢量所在区域的方法,并详细分析了脉冲序列的实现方法,对一些脉冲序列进行了改进,从而再次降低输出谐波。针对能量回馈,结合三电平空间矢量调制进行了系统实验,实验结果验证了方案的正确性。

| Abstract: | Based on the theory of SVPWM for three-level inverter,energy feedback based on SVPWM control algorithm for three-level inverter was proposed.Then the way to apply SVPWM for three-level into inverter was analyzed.Method to calculate the dwell time of voltage vector was given and it was demonstrated that two-level was simply used to judge the located region of three-level preference vector.Then achievement of PWM sequence was analyzed,and some PWM sequences were mended in order to reduce the total harmonics d... |
