Original Abstract Submitted
an object is to separately measure the dc and ac components included in a measurement target current. the current measurement device includes a core, a coil, an element, an ac measurement circuit, a low-pass filter, a current adjustment circuit, and a dc measurement circuit. the core allows magnetic flux to flow therethrough due to the measurement target current. the element generates a feedback voltage, based on the magnetic flux flowing along the core. the ac measurement circuit measures the ac component of the measurement target current, based on the feedback voltage. the current adjustment circuit allows a feedback current to flow through the coil, counteracting the dc component of the core magnetic flux, based on the feedback voltage from which the ac component has been removed by the low-pass filter. the dc measurement circuit measures the dc component of the measurement target current, based on the feedback current.
