Abstract: Different types of oriented silicon steels exhibit different magnetic properties in complicated power electronic equipment operating conditions. For the sake of accurate selection of oriented silicon steel type, the magnetic characteristics of 0.10 mm ultra-thin oriented silicon steel and 0.23 mm ordinary thickness oriented silicon steel were measured under different operating conditions based on the medium frequency Epstein Frame. The magnetic characteristics of two types of oriented silicon steels are revealed. According to the performance under different frequency sinusoidal magnetization, PWM pulse magnetization and special pulse magnetization conditions, the selection suggestions of oriented silicon steel under different operating conditions are given, which provides data support for the design of power electronic equipment.
