New Nanocrystalline Core Performance Versus Finemet(Registered) for High-power Inductors

摘要

Advanced power electronic component development is critical for increasing power density for future military hybrid-electric ground vehicle systems. The design and development of compact, high-power, and high- temperature inductors for a 150 kW, DC-DC bidirectional converter is presented. The converter requires four 25 micronH inductors, each rated for continuous operation at 37.5 kW. With goals of reduced component volume and improved thermal management, inductor performance for commercially available FINEMET(Registered) FT-3M and newly developed HTX-002 nanocrystalline core material is compared.
