ONBOARD MULTIPHASE CONVERTER

摘要

An onboard multiphase converter that has a plurality of boost coils (32, 38) includes annular self-inductance cores (30, 36) which are provided for each of the boost coils and on each of which a corresponding one of the boost coils is wound; and annular mutual inductance cores which are provided for each pair of boost coils selected from the plurality of boost coils, on each of which the paired boost coils are wound and each of which includes a art of each self-inductance core corresponding to the paired boost coils. Each of the self-inductance cores and mutual inductance cores has a gap (34, 40, 42, 44) that divides a line in the circumferential direction thereof.
