<P>PROBLEM TO BE SOLVED: To provide a structure which is capable of being small-sized and reducing the number of parts, and at the same time, capable of achieving low-loss effectively in a reactor for a two or more phase converter. <P>SOLUTION: A reactor 10 for a 2-phase converter which is a reactor for the two or more phase converter comprises two or more phase converter coils 14 and 16 which are wound on a core 12 and coupled magnetically mutually. The core 12 is constituted by combining a plurality of core materials, and in the core 12, the plurality of core materials comprise a coil inner core material constituting at least a part of a portion where the converter coils 14 and 16 are wound, and a coil outer core material constituting a portion where the converter coils 14 and 16 are not wound. The coil inner core material is made to be a low-loss core material in which an increasing degree of a core loss against flux density increase is low compared to the coil outer core material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
