SOFT MAGNETIC CORE FOR POWER FACTOR IMPROVEMENT INDUCTOR PRODUCED FROM PERMALLOY POWDER |
| 摘要 |
PURPOSE: A soft magnetic core is provided to achieve excellent DC superposition characteristics, while reducing total resistance and magnetic core loss. CONSTITUTION: A soft magnetic core contains molybdenum 2 to 4 weight%, nickel 38 to 48 weight% and ferrum. The nickel is dissolved at the temperature of 1650 to 1700 Deg.C for 1 or more hours, and ferrum-molybdenum alloy is added to the resultant structure and dissolved at the temperature of 1700 to 1800 Deg.c. Subsequently, ferrum is added and dissolve.
