| 摘 要： | 有选择性的消谐波脉宽调制Selective H arm onic Elim inated-PW M ,简称SH E-PW M )方法具有开关频率小、输出波形质量好和调制比高的特点,是一种频率最优化的PW M 调制方法。本文在介绍三电平SH E-PW M 方法原理的基础上,讨论了如何采用DSP LF2407A 实现三电平SH E-PW M 调制的问题。实验结果验证了SH E-PW M 方法的特点。

| Abstract: | Since the characteristic of high modulation ratio,high-quality waveform of output voltage and low switch frequency,the technique of SHE-PWM is the most optimal control method. The principle of the control method is introduced,and the realization of this control method is discussed in successfully by DSP LF2407A.The result of the experiment verifies the characteristic of this control method. |
