摘要
在电路设计中电流测量应用十分广泛,测量、保护及控制领域中都有所应用,许多场合对测量的精度要求极高。卫星电源系统中,电源控制器负责电池的管理调节,其应用中常常碰到高共模小信号的测量,分析了常用的测量方法,并提供了一种高精度测量的方法。
The current measurement is widely used in the circuit design, including surveillance, protection and controlment domain, and under some circumstances, extremely high precision is necessary. In the satellite power system, the power control unit is responsible for the management and modulation of battery,and in its application, measuring of small signal with high common-mode voltage is often faced. The commonly used measuring techniques were analyzed in this paper, and provided a solution to get high measuring precision.
