Title:
REACTOR, CORE COMPONENT FOR REACTOR, CONVERTER, AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/125102
Kind Code:
A1
Abstract:
 The reactor (1) according to the present invention contains a coil (2) and a magnetic core (3) on which the coil (2) is placed. In the reactor (1), an inner core part (31) constituting a portion of the magnetic core (3) is composed of a core component (4A, 4B) equipped with: a layered column obtained by layering a plurality of core pieces (31m) and a gap material (31g); and a coating resin (5A, 5B) having a peripheral surface-covering section (51oA, 51oB), which covers the outer peripheral surface of the layered column and retains the core pieces (31m) and the gap material (31g) in an integral state, and an end surface-covering section (51eA), which covers one end surface of the layered column. The end surface-covering section (51eA) accommodates manufacturing errors in the core parts (31m) and the gap material (31g), allowing the core component (4A, 4B) to be formed with a higher degree of precision and to be suitably assembled with the outer core part (32) . As a result, the reactor (1) exhibits superior assemblability.
