摘要: A current sensing circuit has a transformer where to be measured induces magnetic flux into core (12). The magneto-electric converter (28) for DC low frequency signals and secondary winding (18) higher signals. generates an output that is coupled via amplifier non-inverting input of transimpedance (20). inverting the transformer. signal path having resistor (24) couples amplifier. functions as power coupling nulling gain
