摘要

JFE Steel has developed two types of high silicon steel sheets suitable for high frequency applications, JFE Super Core "JNEX-Core" and "JNHF-Core." In this paper, the magnetic properties of JNEX and JNHF are compared with those of thin-gauge grain-oriented electrical steel sheets and iron-based amorphous, which are representative high frequency materials. High frequency reactors were manufactured using each of these materials, and their reactor performance was examined. As results, it was found that JNHF can realize low loss performance in high frequency reactors, as it shows little deterioration in core loss as a result of the core manufacturing process, and can also improve the DC bias characteristics of high frequency reactors, while JNEX makes it possible to realize a large reduction in audible noise in high frequency reactors due to its excellent magnetostriction characteristic.
