【经验】一文告诉你滤高频用小电容,滤低频用大电容的缘由
在电子电路中,经常要用电容来做滤波应用,有经验的老工程师都会说滤高频要用小电容,滤低频要用大电容,很多人就会疑惑,按电容的容抗公式Xc=1/(2πfC)来计算,频率越高,那容抗不是更低吗?这样滤高频不是更好吗? 今天我们就来详细的解释下为什么说滤高频用小电容,滤低频用大电容。
我们假设在下图一电路中,但有一段10kHz的频率从Vin流入时,如果电容是100uF,那么产生的容抗Xc=1/(2*3.14*10000*0.0001)=0.159Ω,当如果电容仅0.1uF,那么产生的容抗Xc=1/(2*3.14*10000*0.0000001)=159Ω.看到这里有些工程师可能更疑惑了,既然100uF的电容阻抗这么小,那么滤高频率不是更好吗?那为什么还要用小容值的电容来滤高频呢?
要搞清这个问题,这就要了解电容在交流电阻中的实际电路结构了,我们先把上面的电路图换个方式,如下图二所示,看到这个电路图是不是还不明白?那我们再把电容换成电阻看看(如下图三所示),现在是不是很眼熟了?这就是一个很典型的分压电路。
没错,其实电容的容抗在交流电路中就相当于一个电阻,它与输入端的电阻组成一个分压器,我们知道,输入电路上的电阻R很小,而且是不变的, 而输出电压Vo=Rxc/(R+Rxc), 当Rxc越小时,其输出端的交流电Vo就越小,滤波效果也就越好。所以说滤高频要用小电容。
反过来,如果在低频电路中,大容值的电容容抗就比小容值的容抗更低,这样在低频电路中其滤波效果就更好。所以我们才会说滤高频用小电容,滤低频用大电容。
