JNEX-Core®, amorphous and ferrite cores are compared for the
inductor of buck-boost converter for Hybrid Electric Vehicles
(HEVs). The core losses are analyzed at the condition of 10kHz
sine wave excitations. Permeability fluctuations vs. temperature
and magnetizing force will be analyzed and discussed. Under the
specifications of buck-boost converter for 20kW THS-II, the
power inductor will be designed with Mega-Flux®, JNEX-Core®
and the informative simulation results will be provided with
respect of dc bias characteristics, core and copper losses.
Keywords- HEVs; Buck-Boost Inductor; High power density;
Low core loss; Thermal stability; Leakage flux
