Dear Friends

Can anyone let me know the best Application note on the "POWER FACTOR CORRECTION"

Input voltage range:90-265vac

Output voltage :360-380V Max

Want to calculate the inductance values as well selection of Magnetics which is easily available in india (Manufacturer would be EPCOS,Cosmo ferrites,Ferroxcube)

let me know good weblinks and articles

Regards
