在恶劣或强电子干扰环境中,比如工业环境和生产装配线等等,在这些系统中,机械设备、高频设备、火花机等等会产出各种干扰和噪声从而影响其它电源的正常工作。出于对净化电源的要求,比如对电源质量要求比较高的精密仪器设备特别是传感器和微弱信号采集的要求,采用直流隔离电源是普通和常用的办法。


直流(或噪声)隔离电源首先是开关电源,纹波和噪声是它的基本问题。如何有效的减少和降低纹波和噪声是直流隔离电源必须面对和解决的问题。本文针对这一问题在实验的基础上做了分析和讨论。


图1是一款Flyback隔离电源的原理图,图2给出了500mA电流输出时的噪声测试结果。

图1:Flyback隔离电源


图2:噪声测试


如果在隔离的两个电源之间增加一个交流通路,则等效于一个低通滤波器。图3给出了带有交流通路的噪声测试结果。从结果可以看出尖峰和高频噪声被减弱。

图3:带有交流通路噪声测试


LC低通滤波器是降低噪声常用和有效的方法。LC虽然可以有效的去除和减弱纹波但同时也会引入新的噪声,这种噪声主要表现为高频尖峰,其大小与输出电流、LC电感和寄生电容等等有关。

图4:带有LC低通滤波器的噪声测试


在开关电源之后跟随一个线性稳压电源LDO)同样可以有效的去除和减弱纹波,取决于LDO的性能同样也会引入新的噪声。如图5。

综上所述,本文讨论了三种去除和降低隔离开关电源噪声的方法,通过这些方法有效的改善了电源产品,取得了良好的效果。电源噪声是一个复杂的系统工程,它不仅涉及到噪声理论,电路设计,电子测量,更依赖于PCB的布板,走线等等工艺过程,这些在此不作讨论。


对于大多数的应用,上述方法基本可以满足,比如数字电路和一般性模拟电路。但对于要求更高的电源比如μV/nA级信号测量,高精密半导体激光器电源和高精度AD/DA转换,仅仅依靠上述方法是不够的。综合多种方法的优化设计可以进一步的改进电源的噪声,图6A/B给出这种电源的测试结果。

如何使用让贴片电感的电源功耗降低?

对于普通开关电源,贴片电感相对于直流12R损耗来说,磁芯损耗几乎可以忽略不计,所以通常情况下,除了“自激频率”这个与频率有关的参数外,电感几乎没有其他与频率相关的参数。但是,对于超低功率,超高频率系统(电池供电设备),这些高频损耗(磁芯损耗和线圈损耗)通常会远远大于直流损耗 。 为了减小开关电源的体积,最好选择尽可能高的开关频率。但是开关损耗以及输出电感的损耗会随着开关频率的提高而增大,而且很有可能称为影响效率的主要因素,真是这些矛盾大大提高了电路设计的难度。 超低功率或着超高功率开关电源的电感,并不像一般开关电源那样容易选择。目前常规的贴片电感都是为了一些主流设计所制造,并不能很好地满足一些特殊设计,典型应用实例就是小体积电池长时间供电设备。
