摘要
以大容量双重化电流源型变频器为研究对象,基于波形、相位及幅值分析,阐明谐波电流产生机理。基于傅里叶级数展开计算,得出各次特征谐波及其有效值,探讨了谐波治理的方法,运行时的实测波形和数据证明了分析和计算的正确性。
This paper focus on large-capacity dual current source inverters,based on analyses of the waveform,phase and amplitude,the generated mechanism of harmonic currents is clarified.The characteristic sub-harmonics and their RMS are obtained by Fourier series expansion,the harmonic suppression methods and mechanisms are discussed.The correctness of analyses and calculations is proved by the measured waveforms and data.
