资料介绍

为了揭示谐波噪声的根源,对传输信号的谐波电流进行比较实验.采用两种主要方法消灭谐波噪声:(1)被动降噪法,即采用旁路、屏蔽、接地、无源或有源滤波方法来限制谐波噪声;(2)主动降噪法,即设计乘法器方式整流电路来改善电子产品开关电源的电压与电流的相位,完成两者同相,减少电源中谐波含量.实践中,使用这些措施去抑制电子产品的谐波噪声,都达到了事半功倍的效果.

In order to reveal the source of harmonic noise, the harmonic current is compared on experimental in the signal of transmission. The harmonic noise is eliminated through two main methods : ( 1 ) The passive method. The harmonic noise is eliminated or coupled or bypassed or shielded on passive and active filter circuit. (2) The active method. The phase of voltage and current are improved on rectifyed circuit in switch power circuits. The phase of voltage and current are both in the switch power circuit. The harmonic content of the power is reduced. In practice, the harmonic noise is suppressed through these measures in circuits of equipment, it has reached a multiplier effort.
