一文详解电源系统中铁氧体磁珠使用
本文中DDY将为大家详细解析电源系统中铁氧体磁珠使用,希望能对各位工程师朋友在进行产品设计的过程中提供帮助。
过滤高频电源噪声并干净地分享相似电源供电轨(即混合信号IC的模拟和数字供电轨),同时在共享的供电轨之间保持高频隔离的一种有效方法是使用铁氧体磁珠。
铁氧体磁珠是无源器件,可在宽频率范围内过滤高频噪声。它在目标频率范围内具有电阻特性,并以热量的形式耗散噪声能量。铁氧体磁珠与供电轨串联,而磁珠的两侧常与电容一起接地。这样便形成了一个低通滤波器网络,进一步降低高频电源噪声。
然而,若系统设计中对铁氧体磁珠使用不当,则会产生不利影响。有一些例子可以说明:由于磁珠和去耦电容搭配用于低通滤波而导致产生干扰谐振;直流偏置电流的依赖性导致磁珠的EMI抑制能力下降。正确理解并充分考虑铁氧体磁珠的特性后,这些问题是可以避免的。
本文讨论系统设计人员在电源系统中使用铁氧体磁珠时的注意事项,比如直流偏置电流变化时的阻抗与频率特性,以及干扰LC谐振效应。最后,为了解决干扰谐振问题,介绍了阻尼技术,并比较了各项阻尼方法的有效性。
为演示铁氧体磁珠作为输出滤波器影响而采用的器件是一款2A/1.2A DC-DC开关调节器,具有独立的正输出和负输出(ADP5071)。文中所用的铁氧体磁珠主要采用芯片类型表贴封装。
铁氧体磁珠简化模型与仿真
铁氧体磁珠能够建模为一个由电阻、电感和电容组成的简化电路,如图1a所示。RDC对应磁珠的直流电阻。CPAR、LBEAD和RAC分别表示寄生电容、磁珠电感和与磁珠有关的交流电阻(交流磁芯损耗)。
铁氧体磁珠可依据三个响应区域分类:感性、阻性和容性。查看ZRX曲线便可确定这些区域(如图1b所示),其中Z表示阻抗、R表示电阻、X表示磁珠的电抗。为了降低高频噪声,磁珠必须处于阻性区域内;电磁干扰(EMI)滤波应用尤其需注意这一点。该元件用作电阻,可阻止高频噪声并以热量的形式耗散。阻性区域出现在磁珠交越频率(X=R)之后,直至磁珠变为容性的那一点为止。此容性点位置为容性电抗(–X)绝对值等于R的频率处。
