Title:
CURRENT DETECTION DEVICE AND POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/131325
Kind Code:
A1
Abstract:
A current detection device (10) is provided with a base body (20), a main conductive body (40), and a detection conductive body (50). The main conductive body (40) and the detection conductive body (50) are formed on the base body (20), and are coupled to each other by means of magnetic field coupling. The detection conductive body (50) is formed inside of the base body (20), and has a spiral shape. The winding axis of the spiral shape is in the direction parallel to first direction. On the base body (20), the main conductive body (40) is outside of the detection conductive body (50), and has a continuous shape in the direction substantially orthogonal to the first direction in the base body (20). The base body (20) is provided with a magnetic material section (30) and a non-magnetic material section (21). The magnetic material section (30) is disposed so as to include a part inside of the winding shape of the detection conductive body (50). The non-magnetic material section (21) is disposed between the main conductive body (40) and the detection conductive body (50).
