Abstract :
In this paper, the characteristics of Mega-Fluxreg, JNEX-Corereg, 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 10 kHz sine wave excitations. Permeability fluctuations vs. temperature and magnetizing force will be analyzed and discussed. Under the specifications of buck-boost converter for 20 kW THS-II, the power inductor will be designed with Mega-Fluxreg, JNEX-Corereg and the informative simulation results will be provided with respect of dc bias characteristics, core and copper losses.
