Low cost powdered iron cores have a gradual saturation characteristic but can intro- duce considerable ac core loss, especially when the inductor value is relatively low and the ripple current is high. Ferrite materials, on the other hand, are more expensive and have an abrupt saturation characteristic with the induc- tance dropping sharply when the peak design current is exceeded. Nevertheless, they are pre- ferred at high switching frequencies because they present very low core loss and the design only needs to prevent saturation. In general, ferrite or molypermalloy materials are better choice for all but the most cost sensitive appli- cations. |
