电源选型任何对元器件、电路板、模块或设备进行测试时都需要使用一个或多个直流电源来给被测物和测试激励源供电；除了给被测物供电外，这些电源有时也可通过模拟被测物工作环境来提供测试激励。比如，多范围的充电机，可以充电12VDC或者24VDC电池组，充电电压会达到28.8VDC左右；针对电子产品，常规测试项目都会包含对产品进行OVP测试，OVP测试所采用的电压通常都会比额定工作电压高1%甚至2%；针对采用额定12VDC电压的汽车电路，但输入电压仍可能高达27VDC，某些汽车标准要求用27VDC的电压对正常工作电压为12VDC的装置进行极限测试。

在为客户提供支持时，我遇到的*常见的问题就是直流感应。直流感应方法很简单，就是安放一个与负载(分流电阻器)串联的电阻器，然后测量整个电阻器的电压(分流电压)。对于频程为10至15倍的负载电流而言，这种方法极为有效。但是低功耗应用需要30倍乃至更高频程的电流感应解决方案。使用线件测量分流电压时，实现这种宽负载电流范围可能很困难。所示的是两个增益如何能够增大可测量负载电流范围。
