This paper presents the design and experimental validation of a 4-phase interleaved mode 2kW 12V- 48V bidirectional Gallium nitride (GaN) converter using a 4-phase coupled inductor based on low- nano-crystalline metal tape material. In a first step the design of this inductor and an analytic volume comparison to standard 4-phase interleaved mode converters is presented. The inductor design will be based on ρ/η-pareto analysis optimizing the design process. Finally the paper concludes in the design of the converter hardware and experimental validation of the system at full load.
