Technical FAQs 4

Are high silicon electrical steel sheets suitable for high frequency reactors?

This paper examines the magnetic properties of JFE Steel’s high silicon electrical steel sheets (Super Core series) as outstanding materials for high frequency reactors, which are important components for realizing energy saving in power equipment, and describes reactor performance when these materials were used in the reac-tor cores. 2.

What type of steel is suitable for high frequency applications?

JFE Steel has developed two types of high silicon steel sheets suitable for high frequency applications, JFE Super Core “JNEX-Core” and “JNHF-Core.”

Why is silicon added to electrical steel sheets?

Silicon is added to electrical steel sheets in order to increase their resistivity. In particular, because the eddy current loss in iron cores rises rapidly as the frequency increases, Si addition is extremely effective in improv-ing the high frequency magnetic properties of electrical steel sheets.

Which steel is used for high frequency transformers?

The Fe–Si alloy sheets included the GT-series of Nikkin Denji and JFE SUPERCORE [ 20, 21 ], which are commercially available steel for high frequency devices. We compared the magnetic flux density (B 8) and core loss (P 0.5/20,000 ), which are magnetic properties that are widely considered for high frequency transformer design.
