感謝網友指正 03:28、04:02 所使用動畫的電路是線性電源而非開關式電源 04:16 為了提高傳統變壓器的功率輸出,理論上有增加單位長度內匝數與增加電流兩種方法。但以實際面考量,會選擇將纏繞銅線換粗一點,增加截面積,降低電阻增加電流,達到功率上升的目的。 也感謝網友補充,除了線圈外,變壓器內的寄生電容與散熱模組,也是相對佔體積的原件,提高工作頻率、更換材料為更好的GaN,也可以降低能耗並減少電容與散熱器的大小。 00:00 iPhone將改用Type-C接頭 00:52 【科科報報】廣告片段 01:22 快充有多快? 02:47 變壓器是如何運作的? 04:10 變壓器的極限 04:52 用高頻變壓降低能耗 06:14 矽材料的工作頻率極限 07:15 GaN為何能取代矽在充電市場中的地位? 08:21 快充協議 09:41 還有哪些半導體新材料? 11:14 半導體新材料的發展 // 延伸閱讀 // 研究發現氮化鎵無毒、具生物相容性 https://pansci.asia/archives/8520 為植入式醫療裝置充電:照光而非更換電池 https://pansci.asia/archives/11170 // 參考資料 // https://www.itri.org.tw/ListStyle.aspx?DisplayStyle=01_content&SiteID=1&MmmID=1071732316365755674&MGID=1073012627765203434 https://epc-co.com/epc/gallium-nitride/what-is-gan https://www.electronics-tutorials.ws/power/switch-mode-power-supply.html https://www.nisshinbo-microdevices.co.jp/en/design-support/basic/02-linear-regulator.html // 製作團隊 // 主持:泛科知識 #鄭國威知識長 企劃:謝富丞 腳本:謝富丞 剪輯:蘇庭緯 想和我們有更多互動嗎?加入會員 ► https://lihi1.com/BWeoe
