【选型】如何为隔离型Buck DC-DC变换电路选择一款合适的电感？
隔离型Buck DC-DC变换电路最核心的隔离器件是隔离变压器，参考如下图1中所示，T为隔离变压器，不过此电路是有设计缺陷的，由于隔离变压器磁芯的磁滞效应，当输入电源Ui为非零直流平均电压的单相脉冲（Ui>0）加到隔离变压器初级绕组上，隔离变压器的线圈电压或电流回到零时，磁芯中的磁通并不回到零，出现“剩磁通”现象，而“剩磁通”的累加可能导致磁芯饱和，故需要做去磁处理。
图1：隔离型Buck变换器典型应用电路
针对去磁改善部分，一般在隔离变压器的初级绕组侧再并联一个串联的初级绕组N3+二极管VD2，具体可参考如下图2所示，此为具有磁复位功能的隔离型Buck DC-DC变换电路，当变压器中出现剩磁通时，可通过初级绕组N3+二极管VD2将残存的能量送到输入端Ui，即进行磁复位。
图2：具有磁复位功能的隔离型Buck DC-DC转换电路
而如上的电路可广泛应用于工业变频、伺服电源的设计，图2中的二次侧的输出电路电路只有1路，当然更常见的是多路输出，本文仅以单路输出做分析设计选型，那么，想针对图2中输出滤波电感L做设计选型，需要知道哪些参数呢？
1、 输入电源电压Ui和输出电源电压Uo
2、 开关管VT的开关频率fs
3、 输出滤波电感L最大纹波电流ΔImax
4、 原边绕组匝数N1
5、 匝比N3/N1
假定某工业变频器的辅助电源是采用图2中具有磁复位功能的隔离型Buck DC-DC转换电路设计，其输入电源电压Ui=220V，二次侧平均输出电压Uo=5V，开关管VT（MOSFET）的开关频率为200kHz，输出滤波电感L最大纹波电流达1A，原边绕组匝数N1为22，匝比N3/N1=1，那么输出滤波电感L可以通过如下公式得到：
电感纹波电流ΔI=Vs * D/（fs*L），其中Vs为电感纹波电压
而电感纹波电压Vs= Ui *（N2/N1）*（1-D）
即：电感纹波电流ΔI=D *[ Ui *（N2/N1）*（1-D）] /（fs * L）--记为公式1；
如上各符号代表含义如下：
ΔI：电感L的纹波电流，ΔImax=1A；
D：代表占空比，未知；
N1：代表原边绕组匝数，N1=22
N2：代表副边绕组匝数，未知；
fs：代表开关管VT的开关频率，fs=200kHz
根据如上的已知的参数，可以得到最大占空比Dmax和副边绕组匝数N2，具体参考如下：
最大占空比Dmax=1/[1+（N3/N1）] =0.5
由公式Uo/Ui=（N2/N1）* D可得，
（N2/N1）min* Dmax=Uo/Ui=5/220
故二次侧绕组最小值（N2）min=N1*（Uo/Ui）/ Dmax=22*（5/220）/0.5=1
根据公式1易得到：
L≥D * Ui *（N2/N1）*（1-D）/（fs *ΔI），将所有已知参数带入即可得出电感值
即L≥0.5 x 220 x （1/22）x（1-0.5）/（200000x1）=0.0125mH=12.5μH
针对如上的需求，推荐选用LAIRD LDZ系列的大功率高饱和电流电感，型号为LDZ2818330K-10，实物图参考如下图2所示，封装尺寸L*W*H为28mm*18mm*28mm，典型电感量为33μH（@500KHz），低至2.86mΩ的极低DCR电阻，饱和电流最大可达9.6A，温升电流达28A，工作温度-40℃~125℃，具体电性参数参考如下图3所示。
图3：LDZ2818330K-10大功率高饱和电流电感实物图
图3：LDZ2818330K-10大功率高饱和电流电感电性参数表
说明一下：
1、 额定电流是饱和电流和温升电流的最低值，即LDZ2818330K-10的额定电流为9.6A。
2、 饱和电流是 DC 电流，在此电流下，电感从其无电流时的值下降 30%。（环境温度 25±5℃）
3、 温度电流为 DC 电流，在此电流下，温度升至 40℃（环境温度 25±5℃）
最后，总结下高电流电感LDZ2818330K-10的竞争优势：
1、 极低的DCR电阻，DCRmax低至2.86mΩ，可最大程度上降低发热损耗。
2、 可承受高电流能力，饱和电流最大可达9.6A，温升电流达28A。
3、 应要求支持定制化设计
4、 工作温度-40℃~125℃
通过如上的介绍，相信大家对隔离型Buck DC-DC转换电路电感选型已经清楚，如果您感兴趣记得收藏和点赞哦，感谢！有问题请留言或电话联系世强400-887-3266。
