無線充電

無線電池充電或無線電感式充電,是不需透過實體電線連接而將電能從充電器傳輸到裝置的方法。無線充電的原理是磁諧振,或電感式電力傳輸 (IPT)。這項程序是透過使用線圈來引發磁場,或將能量從某處傳輸到另一處,如此在兩個物件之間傳輸電流。能量從來源傳輸到接收器,而此接收器通常用來為裝置內的電池充電。


電源電壓轉換為高頻率交流電流,然後以發送器電路傳送到發送器線圈。交流電流會在發送器線圈中引發隨時間變化的磁場。在發送器線圈中流動的電流會引發磁場,而此磁場會延伸到接收器線圈。磁場在裝置的接收器線圈中產生電流。在接收器線圈中流動的電流會由接收器電路轉換為直流電流 (DC),然後用於為電池充電。在發送器與接收器線圈之間傳輸能量流的程序,也稱為磁性或諧振耦合,這是由兩個線圈以相同頻率諧振而達成。


電力透過這種程序穿過氣隙來安全傳輸。也穿過線圈之間可能有的非金屬物件。例如木材、塑膠或花崗石。這使得無線/電感式充電非常適合許多可攜式裝置,例如行動電話和其他無線應用。
