For DC current measurement, a current shunt is place in series in the current path and convert the current to a DC voltage signal.
对于直流电流测量﹐在电流通道串联一电流分流器﹐将电流转换成直流电压信号。

A new equivalence principle of current control for shunt active power filters is introduced, which having no use for measurement of harmonic and reactive currents of nonlinear loads.
