摘要
为了减少逆变器输出波形所含的谐波分量,利用傅里叶变换分析了单相SPWM逆变器死区时间影响输出波形谐波分量的机理,并根据分析提出了如何在TMS320LF2407ADSP芯片上编程抵消其影响的方法。实验结果表明,该方法能使输出波形无畸变,从而验证了分析的正确性和补偿方法的有效性。
In order to reduce the output waveform's harmonic content of a inverter.With Fouier Transform,this paper analyzes the mechanism of the dead-time influence on the harmonic content in the single phase SPWM inverter,and according to the analysis,it also proposes a method which can counteract the dead-tlme influence based on TMS320LF2407A DSP controller.The experiment result shows that the output waveform has little distortion, and proves the correctness of the analysis and the validity of the compensation method.
