| Abstract: | Magnetic separator is commonly applied for removing iron,tungsten reconcentrate and slime dressing in tungsten dressing industry.Excitation current is the primary parameter of magnetic separator and it is produced by SCR（silicon controlled rectifier）.This paper introduces the structure constitution and the work principle of a kind of ＂green＂ high frequency switch power,which can replace SCR.The contrast experiments show this equipment enjoys the features of high transmission efficiency,small volume,light weight and remarkable saving energy effect. |
