Reactor, magnetic core, converter, and power conversion device

Abstract

This reactor comprises: a magnetic core including a core portion which is configured in a prismatic shape; and a coil which includes a first winding portion disposed on the outer periphery of the core portion, and a second winding portion disposed on the outer periphery of the first winding portion. The first winding portion is composed of a first winding wire which is spirally wound along the outer peripheral surface of the core portion. The second winding portion is composed of a second winding wire which is wound along the outer peripheral surface of the first winding portion. The first winding wire and the second winding wire are continuous winding wires. The number of turns of the first winding portion is less than the number of turns of the second winding portion. The outer peripheral surface of the core portion includes a first plane having a plurality of groove portions arranged in a direction along the axis of the core portion. Parts of the first winding wire in each turn of the first winding portion are disposed in respective ones of the plurality of groove portions.
