直流开关电源纹波分析

Analysis of the Ripple in Urban Mass Transit DC Switching Power

对城市轨道交通通信设备的开关直流电源中产生纹波的多种原因进行了定量分析,提出了相应的抑制措施,并且在实验中验证了其方法的有效性和实用性。

There are multiple intrinsic causes of the ripple engendering in the DC switching power. Through simulation and experiment the authors make a quantitative analysis of the ripple, reason its range, and suggest corresponding restraining measure, which, the authors hold to be efficient and practical if put in use.
