摘要
对于 12脉动变流设备产生的非正弦电压和电流 ,用开关函数法分析了其各次谐波的幅值和相位 ,并分别计算了谐波电流含有量和电流总谐波畸变率。分析研究还表明 ,储存环电源交流侧的电流高次谐波的频率是工频电源频率的(12 k± 1)倍 ,其幅值是基波幅值的 1/ (12 k± 1)
The amplitude and phase of harmonics from non sinusoidal voltage and current caused by 12 pulse current converter are analyzed, the content of harmonic currents and the total current distortion rate are calculated respectively. The analysis result shows that the frequency of high order harmonic currents at the AC side of stock ring is 12k±1 times of the fundamental frequency, and its amplitude is 1/(12k±1) times of that of fundamental harmonic.
