Title:
REACTOR
Document Type and Number:
WIPO Patent Application WO/2011/007879
Kind Code:
A1
Abstract:
Provided is a reactor that enables high inductance to be generated with stability in a wide current range, while minimizing noise, processing cost, and eddy-current loss. The reactor (D1) has the ratio (t/W) of the width (W) to the thickness (t) of a conductive member that composes an air-core coil configured to be 1 or less, and preferably, 1/10 or less. Furthermore, the reactor also has the absolute value of a value ((L1-L2)/L3) that has had: the difference (L1 - L2) between; the space interval (L1) between an inner wall face of a first core member (3) and an inner wall face of a second core member (4), at the innermost circumference position of the air-core coil (1); and the space (L2) between the inner wall face of the first core member (3) and the inner wall face of the second core member (4), at the outermost circumference position of the air-core coil (1); divided by an average value (L3); configured to be 1/50 or less. The ratio (R/W) of the radius (R), from the axis-center (O) of the air-core coil (1) to the outer circumference of the air-core coil (1), to the width (W) of the air-core coil (1) (conductive member), is 2 ≤ R/W ≤ 4.
