Publication number: 20220308093Abstract: A current measurement system is configured to measure an alternating-current (AC) current flowing through a conductor. The AC current has a frequency within a measurement range. The system includes a current sensor and a shunt resistor. The current sensor includes a measurement coil configured to be magnetically coupled to the conductor. The shunt resistor has both ends electrically connected to both ends of the measurement coil, respectively. An output voltage across the both ends of the shunt resistor is saturated at a saturation point in a saturation frequency of the frequency of the AC current. An upper limit value of the measurement range including the frequency is higher than a fundamental frequency of the AC current. The saturation frequency is higher than or equal to the upper limit value. The current measurement system improves sensitivity to frequency components higher than the fundamental frequency of the AC current.Type: ApplicationFiled: February 25, 2020Publication date: September 29, 2022Inventors: YUTA SATO, HIROHIDE ICHIHASHI, KAZUTAKA IKEDA
