    降低電感磁芯的損耗

    大家都知道電感磁芯是很多電子產品中都會用於到的一種產品，例如手機

    電感磁芯產生損耗的原因：

    貼tie片pian電dian感gan磁ci芯xin的de損sun耗hao主zhu要yao來lai源yuan於yu磁ci芯xin損sun耗hao和he線xian圈quan損sun耗hao兩liang個ge方fang麵mian，而er且qie這zhe兩liang個ge方fang麵mian的de損sun耗hao量liang的de大da小xiao又you需xu要yao根gen據ju其qi不bu同tong電dian路lu模mo式shi來lai進jin行xing判pan斷duan。其qi中zhong，磁ci芯xin損sun耗hao主zhu要yao是shi因yin為wei磁ci芯xin材cai料liao內nei交jiao替ti磁ci場chang而er產chan生sheng的de，它ta所suo產chan生sheng的de損sun耗hao是shi操cao作zuo頻pin率lv與yu總zong磁ci通tong擺bai幅fu(ΔB)的de函han數shu
，會hui大da大da降jiang低di了le有you效xiao傳chuan導dao損sun耗hao。線xian圈quan損sun耗hao則ze是shi因yin為wei磁ci性xing能neng量liang變bian化hua所suo造zao成cheng的de能neng源yuan耗hao損sun，它ta會hui在zai當dang功gong率lv電dian感gan電dian流liu下xia降jiang時shi，降jiang低di磁ci場chang的de強qiang度du。
