一种利用无源滤波器抑制真空吸尘器的谐波发射电流的方法

谐波是一种干扰信号，在家电设备中由于电气设备本身的非线性，导致谐波电流越来越突出，为了解决这一问题，本文给出了一种低成本的抑制谐波电流的方法，并以小家电吸尘器为测试样品提出了一些解决谐波电流的具体方法。通过实际测量获取大量的数据，针对具体数据进行分析总结谐波超标的原因，最后利用无源滤波器的方法，改进后的测试结果表明选择适当参数的无源滤波器对真空吸尘器的谐波电流的抑制效果较明显。

A passive filter to suppress harmonic emission current of the vacuum cleaner

Harmonic interference signals lead to more and more prominent harmonic current due to the non-linearity of the electrical equipment, appliances, in order to solve this problem, this paper, a low-cost method to suppress harmonic currentand small household appliances vacuum cleaner for the test sample solutions harmonic current. By actual measurement to obtain a large amount of data for the specific data to analyze and summarize excessive harmonic Finally, the use of a passive filter, the test results show that the improved passive filters to select the appropriate parameters for the harmonic current of the vacuum cleaner the inhibitory effect is more apparent.
