| 摘 要： | 传统方法进行直流电源的谐波分析时,存在栅栏效应和频谱泄漏等现象,无法获取准确的谐波参数．为了提高谐波分析精度,这种专门的分析方法通过搜索寻峰,从高幅值到低幅值逐次求出各频率谐波分量参数,每求出一组参数就把该频率谐波分量从测量信号中消去,得出相当准确的结果.

| Abstract: | Conventional methods in harmonic analysis of switching-mode power supplies have many problems, such as frequency aliasing, stockade effect and spectral leakage etc. To improve the precision of harmonic in analysis of direct current power supply, the paper offer a special analysis way, by searching peaks, and find every parameters one by one, from high range to low range, and if one series of parameters was found, the element from the signals measured should be deleted to get the pretty exact result. |
