Abstract

In this paper, Mega Flux^® core is used to establish the buck-boost Inductor for Hybrid Electric Vehicles among potential candidate core materials such as Mega Flux^® core, JNEX^® core and Metglass^®. The buck boost Inductor must have thermal stability, small size, low losses and low EMI noise in automobile applications. Magnetic simulations were tried in terms of magnetic flux saturation level, AC copper loss due to flux leakage and temperature rise at the condition of the water coolant of 65 degrees Celsius. Similar operation tests with HEVs dc-dc converter were fulfilled with established 40kWatt dc-dc converter system. Comparisons between simulation and experimental results will be provided with the temperature rise. Simulation results were verified with experimental thermal configuration.
