Design Method of Coupled Inductor for Multi-Phase Coupled Interleaving Boost Converter

Currently, Interleaving Boost Converters are widely used to achieve high efficiency and minimize the volume of existing Boost Converter. This paper proposes a method for designing a coupled inductor applied to a multiphase interleaving boost converter, which is a more efficient topology, making up for the shortcomings of the existing multiphase interleaving boost converter. It also explains how to derive self-inductance, mutual inductance and coupling coefficients of coupled inductor using the 3D Maxwell analysis tool to determine the availability of the designed coupled inductor and explains how to verify whether the core is saturated.
