摘　　要：对于实际的电源电路系统,通过设计电流检测电路来实现对各路电源电流的实时检测,在电流检测电路设计过程中通常需要对采样电阻和调理电阻的阻值进行选型计算。针对这种比较繁琐且重复性较高的工作,提出利用Excel VBA编写包含串联、并联及比例的阻值选型计算模块技术,能够快速有效地解决电流检测电路中的电阻选型问题。结果表明:使用VBA程序对电阻数据进行选型计算,能够在Excel的工作表单元格上自动生成目标电阻阻值,该方法能够有效地提高采样电阻和调理电阻的阻值选型计算的精度及效率。For the actual power supply circuit system,the current detection circuit is designed to realize the real-time detection of each power supply current.In the process of current detection circuit design,it is usually necessary to select and calculate the resistance values of the sampling resistance and conditioning resistance.In view of this complicated and highly repetitive work,the technology of using Excel VBA to compile resistance selection calculation module including series,parallel and proportion is proposed.It can quickly and effectively solve the problem of resistance selection in current detection circuit.The results show that using VBA program to calculate the resistance data can automatically generate the target resistance value on the Excel worksheet cells.This method can effectively improve the accuracy and efficiency of the resistance selection calculation of the sampling resistance and conditioning resistance.
