Silicon steel is an alloy formed by adding a small amount of silicon (usually below 4.5%) to pure iron, which is called silicon steel. This type of iron core has the highest saturation magnetic induction intensity value of 20000 Gauss; Due to their good magnetic and electrical properties, ease of mass production, low price, and minimal mechanical stress, they have been widely used in the power electronics industry, such as power transformers, distribution transformers, current transformers, and other iron cores.
