Description

When bridge type rectifier and big capacitor filtering are adopted in switching power supply, input current shapesas small top wave, non-line,and input power factor only reaches 0.5~0.7. The current regulations both at homeand abroad stipulates that the input power factor of switch power supply should reach above 0.9,and power factorcorrection must be adopted to improve the factor.At present, normally active power factor is adopted to correctcircuit(such as voltage rising switch circuit),among this system,inductance and filtering inductance are different,this functions as energy storage and transition,which result in different designs.Fe-based Amorphous coreworksas power factor correction inductance,under the conditions of *0KHZ,2.5KVA power factor correction circuit.Compared with silicone steel core with thickness of 0.1,the Core loss drops from *8.8W to 4.4W,and its weightfrom 4.*5KGS to 4.2KGS,so amorphous is the ideal material for PFC inductance.
