Abstract
A current sensor includes: two cores that configure closed magnetic circuits surrounding a conductor where a current to be measured flows and are arranged adjacent to each other; two coils that are wound respectively around the two cores and are connected in series to generate a magnetic flux in surrounding directions opposite to each other in the two cores; an excitation power supply that applies an alternating current with a superimposed direct current to the two coils; and a detection circuit that is connected to a connection point of the two coils. It is possible to obtain the current sensor being capable of high precision measurement up to high frequencies and also capable of reducing power consumption.
