#電源管理 #隔離Isolation #閘極驅動器GateDriver #共模暫態抗擾度CMTI

【All-in-one 閘極驅動器，隔離用電意外】

電子產品在尋求便利之際，電源安全是第一考量！舉凡工廠自動化、消費電子、電梯／空調／電動車等馬達驅動、智慧電網、醫療設備或太陽能電力系統轉換等存在壓差的應用，在將電源或資料從高電壓電路傳輸到低電壓進行通訊時，皆需做隔離 (Isolation，意同「絕緣」)；以承受接地電位差以及與高能量的破壞性接地迴路隔離，避免外來電擊隨電路竄入，造成設備損壞或危及人身安全。

所謂的隔離可分為基本型 (Basic) 和強化型 (Reinforce) 兩種，其中「強化型」即是在兩極做雙重隔離；以牆壁兩孔電源插座為例，表示所連接的地線及火線若轉換時沒做隔離，使用者在碰觸時可能有觸電危險。隔離強度可藉「共模暫態抗擾度」(CMTI) 量化評估，該數值越高越好，代表輸入與輸出的訊號沒有失真；即使在高壓環境中驅動 MOSFET，也不致因外來干擾造成誤動作而引發災難。

具隔離機制的閘極驅動器 (Gate Driver) 因可透過單一器件做引腳配置，驅動多種電路開關架構、實現高速傳輸；加速高頻開關時間能降低開關損耗，且訊號輸入到輸出的傳播延遲時間 (propagation delay time) 僅以「奈秒」計算，方便迅速對控制迴路補償修正。此外，相較於採離散元件設計的 AC-DC 轉換變壓器，可精簡體積，對於資料中心、企業伺服器或電信系統來說，將大幅提高空間運用的「坪效」，創造更多產值。

【雙重隔離，超級守門員】

為免外來電擊隨電路竄入、損壞電子設備或危及人身安全，存在高電壓差的應用皆需做隔離 (Isolation，意同「絕緣」)，以承受接地電位差並與高能量的破壞性接地迴路隔離；其中，「強化型」(Reinforce) 是在兩極做雙重隔離，抗干擾能力更佳。隔離強度可藉「共模暫態抗擾度」(CMTI) 量化評估，該數值越高越好，代表輸入與輸出的訊號沒有失真；即使在高壓環境中驅動 MOSFET，也不致因外來干擾造成誤動作而引發災難。特別標註適用於汽車電子的產品型號，還須留意是否符合 AEC-100 等車規要求。
