Title:
REACTOR, COMPOSITE MATERIAL, REACTOR CORE, CONVERTER, AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/147644
Kind Code:
A1
Abstract:
A reactor (1A) comprises a single coil (2) composed of a winding wire (2w) wound in a spiraling manner, and a magnetic core (3) disposed inside and outside the coil (2) and forming a closed magnetic circuit. The magnetic core (3) comprises an inside core part (31) disposed on the inside of the coil (2), and an outside core part (32) provided so as to cover the outer periphery of the coil (2). The outside core part (32) is configured from a composite material of magnetic powder and a resin. Air bubbles in a cross section of the composite material have a maximum diameter of 300 µm. Due to the air bubbles in the outside core part (32) having a maximum diameter of 300 µm, the reactor (1A) has low loss and the magnetic properties thereof do not readily decrease.
