The DC-DC converter using integrated magnetic components that may achieve high power density has gained attention in environmentally-friendly cars such as electric vehicles (EVs) and hybrid electric vehicles (HEVs). This paper focused on interleaved boost converters using close-coupled inductors and loose-coupled inductors that are the integrated magnetic components. Following, detailed electromagnetically analysis for these circuit types were conducted in order to calculate volume of inductors and capacitors that are occupied the large part of space in the converters. The total volume of inductors and capacitors in these circuits were demonstrated clearly through comparison with conventional circuits such as an interleaved boost converter and a single-phase boost converter. As a result, it became clear that interleaved boost converter using loose-coupled inductors was effective for miniaturization of total volume. Further, duty ratio of the minimum volume of close-coupled inductors method is different from the duty ratio of the minimum volume of loose-coupled inductor method.
