Lightweight and compact high-power-density boost converters are required for many applications. This paper presents a three-phase interleaved boost converter with a novel coupled inductor that can achieve high-power-density. The novel coupled inductor is especially suitable for the three-phase interleaved boost converter, from the core structure standpoint. The electrical and magnetic characteristics of the three-phase interleaved boost converter are analyzed in detail to illustrate the effectiveness of the novel coupled inductor. Furthermore, maximum output power calculation methods for the novel coupled inductor and a non-coupled inductor are proposed to demonstrate the performance of high-power-density converters. On the basis of the calculation method, the maximum output power of the proposed coupled inductor is about 2.6 times greater than that of the non-coupled inductor under continuous current mode (CCM) conditions. The compact volume, low-weight characteristics, and the performance of the three-phase interleaved boost converter with the novel coupled inductor are discussed from both the theoretical and experimental standpoints.
