摘要
分析了几种电控单元(ECU)电源系统的特点,介绍了电源芯片的选择方法,通过对电源模块印刷线路板(PCB)的布局布线分析,解释了电磁干扰(EMI)相关问题,并且给出了电源系统中电感值的计算方法。
Analyse the characteristic of some kinds of ECU's power system,introduce the selection method of power chip.Through the PCB layout analysis of power model,explain the problems about EMI.Also it provides the method of how to calculate the inductance's value in power system.
