“…As a common device, an inductor is widely used in power conversion systems, but its leakage magnetic flux generates one of main radiated EMI sources. Therefore, an improved EMI design has to be achieved to reduce leakage magnetic flux from the gap of an inductor [1]- [5].…”

In this paper, the electromagnetic interference reduction effect of a magnetorheological (MR) fluid-gap inductor in a dc/dc converter is investigated. For a realistic electromagnetic simulation, a prototype MR fluid-gap inductor is built and put in a typical buck converter setup, and the current waveform of the inductor is measured. Based on the measured current waveform, a 3-D time domain finite element electromagnetic analysis is performed considering non-linearity of an MR fluid and complex geometry of the winding. The rms and maximum values of the leakage flux and eddy current losses of the MR fluid-gap inductor are calculated and compared with those of the air-gap inductor. It is predicted that the eddy current heat source due to the leakage flux from the gap is reduced by as much as 75.6% for the MR fluid-gap inductor. To verify the simulation data, the leakage fluxes of both MR fluid-gap and air-gap types of inductors are measured in a dc/dc converter setup, and their experimental results are compared with calculated ones. Index Terms-Electromagnetic interference (EMI), leakage flux, magnetorheological (MR) fluid, variable inductor.

“…The silicon steel (6.5% Si‐Fe) has been used as a core of power inductors for EV applications [10]. Nonetheless, this core material needs discrete air gap, which may affect the losses due to EMI and induction heating due to astray flux [29]. Similarly, other magnetic cores such as ferrite, amorphous alloy, and nanocrystalline have the same issues.…”

In power powertrain, DC-DC converters, the selection of suitable magnetic core materials is a critical design consideration. It ensures weight and volume reduction and performance enhancement of such types of converters. This study provides a comprehensive comparison of magnetic core materials and a simplified cobweb chart that aids in the initial selection of magnetic core materials for powertrain DC-DC converters. The weighted property method (WPM) is used to systematically select and rank the suitability of the magnetic core materials, and a multi-attribute decision-making analytical hierarchy processes is used to calculate the relative weight of different properties. Based on the peculiar requirements of powertrain DC-DC converters, the most suitable magnetic core materials are identified and ranked with the help of the cobweb chart and the WPM. This study aims at providing a quick reference for designers to ease the selection of suitable magnetic core material for powertrain DC-DC converters.
