磁环电感精确计算表格xls世纪电源网 电源行业门户 资讯

1、使使用用说说明明：以铁硅铝第一列（E列）为例绿色部分为设计需要的输入的参数，电流2.5A，匝数168浅蓝色部分为磁环参数，从厂家手册里找到相关的数据填进去这个环型号是77894，是个27mm的铁硅铝环橙色部分是计算结果改变绿色部分的值，就得出不同的计算结果其中控制指标是导磁比，最佳在50%,不能太小.如果太大，说明磁环用大了导磁比也就是饱和深度，以50%为最佳然后看导线截面合适不, 和自己按载流密度估计的数相比如果计算出的导线截面太大，说明窗口有多余如果计算出的导线截面太小，说明窗口小了，也就是磁环小了这个导线截面是按饶满计算的检测参数是空载检测读数，这个电感检测数应该是出厂感量1.95mH为

2、合格设计电感量为975uH, 电流可以过2.5A橙色部分是自动计算出来的，不要改里面的公式，关键算法是根据厂家提供的概化曲线方程式写成的表格中还有一些中间(红色)或参考数据栏, 可以(已经)隐藏掉,但是不能删除.最下面还提供了双环叠用时的参数，更多的叠用以此类推可以采用列复制的方法任意增加计算列, 这样可以永久保留设计资料和充分利用已有的磁环数据.导线长度是近似的，批量生产可能需要适当修正暂时没有提供磁环损耗的计算方法，厂家资料也提供有相关概化曲线方程式，有兴趣的人可以加进去磁环损耗主要是与频率有关，不想引入太多的初始数据，目前就电流和匝数2个参数，即可确定一个电感最上面是厂家提供的磁环初选图

3、表，可以参考，也可以不予理会需要说明的是: 电流为偏置电流，即直流成分的意思对于含有比较大的交流成分的情况(即纹波大)，还需要根据峰值电流校核饱和深度和对应感量，甚至可以根据这个算法(迭代)得出实际电流曲线.事实上, 这个计算表格的特点就是可以按厂家的技术标准和电感的实际工况精确计算出电感的感量以及磁芯的饱和深度其中没有任何人为总结或推导(任意性很大)的经验数据参与计算, 也不需要查图(烦琐且没有精度)或试算,磁环选择就看厂家手册了，不同的材质、尺寸得出不同的结果一般动态电流大就用铁硅铝，比如Boost电感(注意:铁硅铝仍然有饱和的可能).动态电流小就用铁粉芯，比如滤波电感，便宜，且不会饱和.

4、磁环损耗与动态和频率有关，且主要是动态，因此即使是很高的频率，只要动态很小（滤波电感通常如此），就没有必要用铁硅铝。使用什么材质其实只有一个原则：不发热为准本计算表格的基本算法来自于:铁粉芯: 微金(MICROMETALS)的功率磁芯(Iron Powder Cores)数据手册合金粉芯: 美磁(MAGNETICS)的功率磁芯(Powder Cores)数据手册因此,磁芯的参数也应该以这两家的数据为准, 其他厂家的磁芯能不能按此表格计算,取决于他们与这两家产品标准的一致性. 补充：手册提供的铁硅铝损耗计算公式是 ，其中B=V/(4.44NFAe)-别人提供的计算公式。 铁硅铝计算表格里磁芯损耗

5、就是根据上述公式得到的，这需要输入磁环电感两端的电压V和频率F，不知道对不对？微微金金铁铁粉粉芯芯特特性性表表材料导磁率密度成本颜色0温度系数Al离散性(0) (g/cm3)(+ppm/C)(+-)-21052.7红/无955%-8356.55黄/红25510%-14145.23.6黑/红15010%-18556.63.4绿/红38510%-19556.81.7红/绿65010%-267571黄/白82510%-302261.4绿/灰51010%-34336.21.5灰/蓝56510%-35336.31.4黄/灰66510%-40606.91绿/黄95010%-451007.22.6黑/黑10
