Title:
REACTOR DEVICE
Document Type and Number:
Japanese Patent JP2021019104
Kind Code:
A
Abstract:
To provide a reactor device that is a magnetic coupling type reactor device, and can reduce magnetic loss and occurrence of magnetic saturation by preventing magnetic concentration while ensuring a desired leakage inductance value.SOLUTION: A reactor body 100 includes: outer leg cores 101A2, 101B2, 101C2, and 101D2 disposed both sides of left and right; a pair of base cores 101A1, 101B1, 101C1, and 101D1 each connecting both ends of the outer leg cores; a core portion made up of two middle leg cores 101B3 and the like disposed to be erected between the outer leg cores; and coil portions 103A and 103B wound around the middle leg cores. The middle leg cores form a magnetic path for mutual inductance generated by the coil portions 103A and 103B, and the outer leg cores form a magnetic path for leakage inductance generated by the coil portions 103A and 103B.SELECTED DRAWING: Figure 1
