Özet:

DC-DC power electronics converters are used in many applications such as electric vehicles, energy storage systems, renewable energy sources. The inductors designed for a specific frequency and current level have significant impact on the converter performance. In this study, an inductor is designed for a specific frequency and current value with some common core geometric structures called EE, block, pot and toroidal. Since inductors operate at high frequency values, the Kool-Mu which is a kind of powder core is selected. The Kool-Mu has distributed homogeneous air gaps and is used inductor designs that saturation is not desired. Inductors are designed for EE core, toroidal core, pot core and block core structures. Electromagnetic modelling of these inductors designed for different core structures are carried out with finite element analysis (FEA), and induction stability, core and winding losses, mechanical specifications and flow distribution have been comparatively. In addition, some suggestions are derived in core structure definitions for DC-DC converter inductor design.
