Abstract
A reactor that can suppress an increase in ripple current even when electric current imbalance occurs is provided. A reactorincludes an annular coreformed by a magnetic body, and two coilswhich are attached and magnetically joined to the annular coreand which generate magnetic fluxes in directions opposite to each other. The differential permeability of the annular coreat 5000 A/m is equal to or more than 30% of the maximum differential permeability of the annular core
