DC-DC power electronics
converters are used in many applications such as electrical vehicles, energy
storage systems, renewable energy sources. The inductors designed for a
specific frequency and current level have significant impact on 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 in 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
inductance stability, core and winding losses, mechanical specifications and
flux distributions have been reported comparatively. In addition, some
suggestions are derived in core structure definitions for DC-DC converter
inductor design.
