Title:
REACTOR, CORE MEMBER, AND POWER SUPPLY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/142755
Kind Code:
A1
Abstract:
Provided are a reactor, a core member, and a power supply circuit with which the size of the reactor can be reduced. A reactor (1) is provided with a first coil (21), a second coil (22), a coupling core unit (30), a first core unit (31), and a second core unit (32). The coupling core unit (30), through which magnetic flux generated by the first coil (21) when the first coil (21) is electrified and magnetic flux generated by the second coil (22) when the second coil (22) is electrified pass, magnetically couples the first coil (21) and the second coil (22) so as to form a coupled magnetic path along the coupling surface. The first core unit (31), through which magnetic flux generated by the first coil (21) when the first coil (21) is electrified passes, forms a first magnetic pathway along a first surface. The second core unit (32), through which magnetic flux generated by the second coil (22) when the second coil (22) is electrified passes, forms a second magnetic pathway along a second surface. The coupling surface is orthogonal to the first surface and the second surface.
