Document Type and Number:
WIPO Patent Application WO/2019/123790
Kind Code:
A1
Abstract:
Provided is a reactor equipped with a current sensor in which linearity can be maintained in the relationship between magnetic flux density and input electromotive force. An annular core 11 has: two leg parts 1a disposed in parallel; and two yoke parts 1b disposed to connect end sections of the two leg parts 1a. A coil 2 is mounted on at least one of the leg parts 1a. In a corner section between the leg parts 1a and yoke parts 1b, a sensor core 3 protrudes further toward the outside of the annular core 11 than the outer circumferential surface of the annular core 11. A notch 3a is provided in the sensor core 3. A magnetic field detection element 5 of the current sensor is mounted inside the notch 3a.
