| Abstract: | Sendust core has been widely used for its high saturation magnetic flux density,good high-frequency magnetic properties and low power loss,low cost,etc.In this paper,sendust core was applied to boost inductor,and iterative method was adopted to optimize the selection of sendust cores.The design process of sendust core was summarized,and example given confirmed that sendust core can not easily reach saturation and has low power loss in condition of high current. |
