摘　　要：提出采用小波分析实现谐波电压和电流在线反馈跟踪,以谐波分量最小优化控制方式,使逆变器在整个输出频率范围内保持谐波最小的最佳工作。实验检测表明,在谐波最小情况下,全频率范围调节输出电流正弦度良好,电动机发热现象明显减小。Adopting the wavelet analysis to realize the feedback and track online of harmonic voltage and current was presented in this paper, in which using optimized control way of minimal harmonic component to keep optimal working of the inverter in the whole output frequency, the good checking results and wide use-value were proved.

关 键 词：小波分析 逆变技术 谐波
